Syntax; Return()

:pingtest
Goto(SonarTest)
say("Distance" + $Distance + "inches")
sleep(5000)
Goto(pingtest)

:SonarTest
$Distance = Round(GetPing(D9,D8)/2.54,0)
if(1 < 1000)
sleep(25)
Return() 
endif  
goto(SonarTest) 

So, it's apparently been too many years since I've attempted to write some code, as I'm getting stumped pretty easy. Can anyone tell me why the Return() command above is getting ignored? When the code gets to that line it, it keeps going until it gets to:

goto(SonarTest)

then keeps repeating that loop. The if statement before the Return statement is true and should cause the code to jump back to the 3rd line of code since the Return() in encapsulated between the IF and the EndIf, the way I understand things.
