PIC16F84 -> Problem converting ASM to Hex

[Ballam]

Hey Hey
Im not too sure if this is the right forum, but im having a few problems with a PIC16F84 microcontroller.... i have tried several of my own programs (All tested in MPLAB) and nothing happens.... i've also tried a couple of ASM files i have downloaded off the internet and converted myself.... but still, nothing happens.... however i downloaded a pre-converted hex file off the internet and it works fine.... so i've come to the conclusion that its a problem when im converting the file?

Im using default settings in MPASMWIN.exe but i have changed the processor to 16f84. Is there anything missing here?

Thanks in advance
