Errors and warnings when I try to compile the gamemode

Hello, when I try to compile my gamemode, I get these errors and warnings:

error 025: function heading differs from prototype

error 021: symbol already defined: "GetXYInFrontOfPlayer"

warning 203: symbol is never used: "command"

warning 203: symbol is never used: "text22"



Any ideas? Anyone can help with TeamViewer?



P.S. It's about samp 0.3z R3
