Find beta and p in interaction +-1SD

Hello, i have a question about interaction in å hierarcical multiple regression. I want to find the beta and p value for the interaction when the moderator is + and - 1 SD from mean.
I have tried prosess Marco om spss, but i can only find beta and p value for the moderator at mean and +-1SD from mean. I have also tried to make two new interaction, one with moderator 1 SD above and one 1SD below mean. When i used this meg god, both beta values were higher then the mean leveled interaction. What am i doing wrong? And how can i find beta and p for the interaction when moderator is +-1SD?
