Looked a bit through your code, and added some comments in your code.
Maybe it helps, I did my best to help you.

// when you use the if function, you can only use one native. For example:
// IsPlayerInRangeOfPoint(playerid, range, X, Y, Z) || IsPlayerInrangeOfPoint(playerid, range, X, Y, Z)
// So close the native before you want to use the "or" function or "equals" function.

// Also, the latest parameter in IsPlayerInRangeOfPoint is missing. You're missing a Z-coord.
