"WebX2 is a dummy coded predictor, and the model contains an interaction term for X1*X2. The B value for the intercept is the mean value of X1 only for the reference group. The mean value of X1 for the comparison group is the intercept plus the coefficient for X2. It’s hard to give an example because it really depends on how X1 and X2 are coded.
