I have a form that has 10 fields on it.  I have made all of them "Required". 
I also am using vb if statements to decide whether or not each field should 
be on the page.  I am using the vb to compare values in my database and if a 
certain field equals something then the field is shown on the form.  When 
the form is displayed in the browser, it could any increment of the 10 
fields on it.  My problem is that unless all fields are being shown then the 
validation does not work and the form submits even with blank fields.  Has 
anyone tackled this kind of a situation before and if so how did they 
accomplish it?  Thanks in advance for your help!

Use Javascript, it's better than VBScript.
Or go to alt.comp.lang.vbscript

I think that I explained this wrong in my first post.  I am using javascript 
to validate the forms and asp if statements to decide which form show on the 
page.  The problem it that the javascript is not working unless all of the 
form fields are visible on the page.

Meaning what?
ASP.NET?

The browser doesn't see server-side code.

Which runs on the server, and which the client?
This group is for javascript. If the problem is with the VB on the server, 
posting here doesn't help much unless one of us who knows VB decides to go 
ahead and answer an OT question.

Post your .NET code and I'll check it out.
Providing a URL so I can see what the browser gets is also helpful.

Without a little more information, it's hard to understand where your
problem might be.

Here's my understanding:
Your ASP is conditionally outputting form fields. In many cases, a form
field simply won't exist in the HTML that is being output.

Your JavaScript form validation is broken-- it will only validate
properly if ALL fields exist on the page, which is rarely the case.


If this is correct, you need to add to your validation a check to see
if the element exists. If it does, validate its value. If it does not,
skip it and/or consider it valid.

This check is fairly simple since JavaScript is so tolerant. If an
element exists, it evaluates to true. If it does not, it will not.

if( document.forms[ myForm ].elements[ myElement ] )
   validate( myElement );

  Form validation is usually done from the form onsubmit event:

  <form ... onsubmit="return validateForm(this);" ...>

  The validateForm() function tests whatever, then returns true or false
  depending on the success or failure of the validation.  If false is
  returned, the form won't be submitted (at least, that's the theory).

  Please remember that the fact that your forum subsequently submits does
  not mean it actually passed validation, you can't guarantee that at
  all.  The user may have JavaScript disabled or may have bypassed your
  validation routine some other way.  Check everything again on the
  server.

  Your validateForm() function may go something like:

  function validateForm(f){
    var formElements = f.elements;
    var formValid = true;
    var i = 0;
    if ( formElements[i] ){
      var el = formElements[i];
      do {
        if ( 'someElementName' == el.name ) {
          /* do validation for this element, if it fails:
           *
           *  formValid = false;
           *
          */
        }
        if ( 'anotherElementName' == el.name ) {
          /* do validation for this element, if it fails:
           *
           *  formValid = false;
           *
          */
        }
      } while ( (el = formElements[++i]) )
    }
    return formValid;
  }

  You may wish to use 'switch' (JavaScript's version of 'case') instead
  of if's, that's up to you.  It is also handy to base your 'if' on the
  className, say if you have lots of text fields that you just want to
  check that they have something in them:

        if ( 'plainText' == el.className && '' == el.value ) {
          formValid = false;
        }

  In your HTML:

      <input type="text" class="plainText" ... >

  The className 'plainText' doesn't have to be defined anywhere, just set
  on the element. You can cope with multiple class names too, it just
  takes a little more effort (and is a tad slower also):

        if ( /\bplainText\b/.test(el.className) && '' == el.value ) {
          formValid = false;
        }


  Have fun.

	Yes, VBS is only for Internet Explorer browser and in windows 32bit  
platforms, so, won't work in say macOS IE, whereas javascript will do fine  
in any browser/platform.  What you need is select this or that element and  
then more options are shown, that were not there Unless you do  
choose/select/tick/check/uncheck/else that element, very easily done in js  
by using the objects style stack, if (SOANDSOHAPPENS)   
{ obj.style.display='none'} else { obj.style.display='inline' /// or  
'block' whicheve the box happens to be}.  Peruse around at
