SPSS 13.0 Student version: variables not showing up!

#1
I am trying to run a One-Way ANOVA under "Compare Means" and only the first 7 variables from Data Editor are showing up for me to use.
I also wanted to run Descriptives and the same thing happened there!
I found an ANOVA table that could be run under the "Means" section of "Compare Means," but can't run a Levene's statistic for Homog. of Variances from there.
Anyway, I want all of my variables to show up regardless of the dialogue box I use!
Please help! I'm ready to cry.
Thanks.
Karen
