### newbie, eviews7, how to interact two dummy variables?

I end up getting N/A for some of the values?

I have two sets of dummy variables, one of them is gender (female=0 male=1) the other is a salesperson (salesperson B=1 salesperson A=0) how do I go about generating an interaction variable for them?

Yup thats what I did, I assume that N/A values are generated from 0*0? can I still run a regression on that?

0*0 = 0

No, 0*0 will give you zero. You probably have NA values in one of your dummies.
