I am plotting coefficients of regression analyses and one of the models has an interaction term between a continuous and a categorical variable. for some weird reason, in the coefplot graph the coefficient does not appear. what am I doing wrong? I have tried everything, and read instructions, but in vain. thanks a lot in advance. my commands:

quietly reg standard_postcc c.disagreement agreement individualdisagreement individualagreement standard_cc ib(last).gender age,cluster( group_num )
estimates store a
