I just started evolving with SPSS a few weeks ago. Let’s say I want to do a statistical test to check the efficiency of 4 different pesticides over 5 weeks (the first week is the control). Every week, we take measurements. I decided to go with the two-way repeated measures ANOVA test
(Analyze--> General linear model--> Repeated measurement's selection). My issue is coming up when I have to add the second factor (I added the first factor as a five level). No matter how I insert my data, adding the second factor is impossible.

Am I using the wrong test or messing up with the settings? Thanks for any help you can provide!
