final project
i recoded variables to dichotomous variables and since I have, I no longer get any values for the interaction between variables- the main effects are there but interaction effects are blank. Can someone please let me know if this is okay/normal or what I could have done wrong and how to fix this? Is there another way that I can test for interaction effects?

No, this isn't a good thing at all.
Look at your descriptive data and make sure that all your cells are filled.
Crossing two (or more) dichotomous variables should give you interaction effects.
