Hello SPSS Experts, 

I apologize for the novice question but I have 3 independent variables (A, B, and C) that are highly correlated and I want to calculate the interaction term for these 3 variables (one DV within). I am new to SPSS and I'm not sure how to calculate the interaction between A*B*C. I have included some mock data below and would appreciate any help. 

Cheers, 

R
