repeated measure anova error

[Eva]

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?

That's likely. I've accidentally had groups identified as
something other than "1" and "2" that my setup required.

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.

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.
