Function Not Working

programming flash

I don’t get why my menu dropdown function is not working. It works when I put the instance name of the dropdown menu in, but when I try to use eval for the instance name it won’t work. This code is giving me the problem.


menuopen(eval("d"+q), -219, 0);

This is most of my AS
