May be have bit of a read of http://wiki.gromacs.org/index.php/Category:Force_Fields and the manual, so you can get a grip on what forcefields actually are and how you use them.
I get the impression you are trying to do things here without actually understanding or even thinking about what you are doing. Things are NOT plug and play here, you actually have to think and work things out. Take a step back for a moment, do some reading, have a play with some tutorials, then go back and address the problem you looking to research.
