How to make a character do two animations back to back without an error?

Hi, I want my character to cough and then to think_rubchin afterwards. How would I code this?

@CHAR is cough THEN CHAR is think_rubchin

@CHARACTER is cough
@CHARACTER is think_rubchin
@CHARACTER is cough THEN CHARACTER is think_rubchin

and if you want another character do something at the same time as that you can use one of these things & instead of an @ symbol before these lines of code. For example.

&CHARACTER1 is idle
@CHARACTER2 is cough THEN CHARACTER2 is think_rubchin
