Oh, save their score before they teleport, and check the different afterwards.

pawn Код:

OldCash[playerid] = GetPlayerCash(playerid)
Put that where they teleport

NewCash[playerid] = GetPlayerCash(playerid)
Put that after they've done it all
Then do whatever checks you want to do with NewCash & OldCash

Is that what you wanted?

EDIT:

pawn Код:

new OldCash[MAX_PLAYERS],NewCash[MAX_PLAYERS] 
Put that at top of scriprt

EDIT2:
To activate it, when he teleports, run a timer, or something, and to disable it again, KillTimer();
