This can happen when you fail to have a plug-in and or resource the script depends on. If this is the case, nothing will work on that filterscript. Try using a blank filterscript with only what you need, and it should work. For example,

pawn Код:

#include a_samp
#include zcmd

CMD:heal(playerid, params[]) { return SetPlayerHealth(playerid, 100); }

If it's not working then I'd recommend you re-download the latest SA-MP package.
