Units - Using the full data set

[Justkeepswimming]

Hello,

I am new to the forum and hoping for some guidance. I am coming up against an error when comparing groups (repeated measures (time)).
I have had the error previously but can not remember how to over come it.

Within Units, I only seen to be able to access 1 of X, rather than the entire data set. When I check the equation against previous (when it worked) I have a comma between Level 1 and Level 2. Which I did not have before (when I had equations which worked), how do I remove this comma?

If this makes any sense to you, do you know what I am doing wrong and how to resolve is?

Thank you in advance

Could you check in the "Names" window that all of the columns used in the model (including the column "cons") are the same length? It sounds like you may have one included that only contains one row, which would result in this length being used when calculating the number of units.
