isPlayerInRangeofPoint - AHK Issue

[NF22]

I'm trying to make AHK script that will check my position and run a command if I'm in the range of the point. I can't seem to get it work. This is the code I have so far. Should I use while? Any help would be great!

#include SAMP.ahk

!f::
StopF :=
Loop,
{
If (StopF = "")
    {
        sendinput,{esc}t/fish{enter}
        sendinput,{esc}t/myfish{enter}
        Sleep 11200
    }
}

if(IsPlayerInRangeOfPoint(2143.3135,-119.9903,-0.0992,5.0)){
        sendinput,{esc}t/sell{enter}
        sleep 2000
    }

RETURN

^f::
StopF := 1
