Hi AFNI Heroes -

I'm having some trouble with a 3dANOVA3 script. The study has 2 groups (younger, older) and 2 levels of encstrat (sentence, image) and 18 subjects overall (9 per group). After correcting my script for a variety of other errors, I am getting one I can't seem to fix: "must have equal sample sizes for 3dANOVA3"

I think I DO have equal sample sizes. Any help would be greatly appreciated!

Here is the script pasted, as well:

I don't think I need to specify that I am new to this. :)
