Hi,

I have obtained the force field paramter of a small molecule (parameterized for CHARMM FF) and now I want to ad this to the charmm force field so that i can use it for simulation . I searched gmx userlist but didn't find any appropriate thread.. can anybody let me know ??

I find that hard to believe.  Ligand issues are dealt with weekly, if not daily.

If you have all the parameters, #include your ligand .itp file in your .top. No modification of the force field files is necessary to do this. Chapter 5 of the manual is your best resource.
