Looping on a variable number of functions

I'm writing a program that needs to perform operations on a variable number of equations which will be named g1(X), g2(X),....,gm(X) . I tried to use a for loop to cycle through the functions, but mathcad ends up looking for a function called gi(X), which doesn't exist. Is there any work around for this. See the attached file for the relevant chunk of the code. Thanks
