Make the code smaller. I think. Code please?

The most likely issue is a code size limit of 2k instructions on your version of MikroC Compiler.

According to MikroE's website:

Download and try out the software - FOR FREE! Software is equipped with fully functional demo license with up to 2K of program words of output code size which can be just enough for simple applications.

The PIC16F877A has 8k words of Flash, program memory, so program storage is not an issue in this case.

How large do you suppose your file is? You could be able to trim it down to fit.
