Here is some code I wrote. I dont why its giving me these errors.
C:\My Documents\programs\actual project for ie1.cpp(55) : error C2064: term does not evaluate to a function

I cant get any of those errors fixed. Could someone help me. I'm sorry its so long but I didnt know what all you would need because I dont know whats wrong.
Heres the code: (its long)
