repeated measure anova error - comp.soft-sys.stat.spss

I keep running across this error when I try to run my SPSS model: "no valid cases found. this command cannot be executed." I am told this is probably because I didn't merge or code my variables properly. How do I track where my error is? Thanks. I can post more output if helpful.

What syntax are you using to do this?

The GUI (graphic user interface) is a great way to get the first draft of your syntax. Go through your clicks in the interface and exit via <paste>. You can then copy that syntax into a mail message. Also please describe what you are trying to do. How many and what between subjects factors do you have if any? How many and what within subjects factors? How many levels in each factor? Do you only have two repeats of the DV for each subject? What do you get when you do MEANS on your DVs by your between subjects factors?

How do I track where my error is? That's likely. I've accidentally had groups identified as something other than "1" and "2" that my setup required. > >Thanks. I can post more output if helpful. Do what Art suggests. The other possibility is that you have a systematically missing data, so that no case is complete for all the replications. Repeated Measures will (properly) drop every case that is not complete. -- Rich Ulrich

It is better if you include the newsgroup and/or list in your posts. 1) It builds up the archives so that people with a similar problem in the future can find it. 2) more people will see your posts and the replies and can add more suggestions 3) the person who replies may not get back to the newsgroup/list as quickly as other members. Check which dataset should be activated. click <windows> and look at the contents of the different datasets you have open.
