Your if() is wrongly intended 3 lines above your error.

Also, golden rule in programming, whenever you're repeating large chunks of code, you're doing it wrong.

I want to explain to you about Boolean operators.

Boolean has two possible values: TRUE and FALSE.
In BYOND, FALSE is either 0, null or an empty string ""
TRUE is anything but a FALSE value (ex: referenced object, number, string, etc.)

if(val)
  If the value is true, do this (meaning it is anything but 0, "", null)

if(!val)
  If the value is false, do this

if(val == 2)
   if value is exactly 2, do this ((val==2) will return 1 (TRUE)).

So where you had if(TP==0||TP==null||!TP), all you need is if(!TP)

In addition, the while() statement you used is useless. Once return is called, the procedure stops which means that the while() is not called. What were you attempting to do? while() is like saying: 
while(condition)
  Do this

Is the same thing as:

LOOP
if(condition)
   Do this
   goto LOOP

Ultimately useless in the way you had it.
