Questionnaire data with multiple categories.. urgent!

I have the following issue by using SPSS analyzing my data of a questionnaire:

I have 16 questions (7point likert scale, with 4 categories with 4 questions each) applied in 2 conditions for each subject, so each subject filled in the questionnaire in 2 different conditions. Now I want to compare the average each category between the conditions to show that these were different. I thought of using an ANOVA, repeated measures, but I am not sure how to handle the data (how to type them in SPSS) and how to make the ANOVA properly..

Could someone help me? :confused:
