FIR compiler II and coef_set[]

Hi people

I've just started using FIR Compiler II. Please can anyone tell me how to control which coefficient set is used?

I have bee able to tell the compiler about my eight different sets of coefficients and it shows them in the wizard but I cannot se any control signals generated that allow the coefficient set to be selected.

In FIR Compiler this was coef_set[]

Please help.

Thanks
