pawn Код:

if(!IsPlayerInRangeOfPoint(playerid, 10, 1526, -1676, 5.89) || !IsPlayerInRangeOfPoint(playerid, 10, 613.8015, -589.0556,17.2330)) return SendClientMessage(playerid, -1, "You are not at the arrest point.");

You cannot have an if inside if like that:

pawn Код:

if( something || if( something2 ) )
// Not correct

And instead of closing the parentheses and return an error message, you use "||".

Anyways, the last IsPlayerInRangeOfPoint was a bit.. 4 parameters (x, y, z, angle) and I think the previous parameter was skin instead of the range. I suppose it's if he's not in that range the second as well.
