Not getting one-shot inside IF...THEN

[Joseph 0028]

Hello Folks... The pictures show it all... I just need to produce a one-shot inside the IF...THEN, and the Oneshot's input bit goes from 0 to 1 as you see from the trend, but the output bit is not going to 1, or giving a pulse ? can anyone help me understand why i am not getting a pulse in this code ?

And is there another easy way to get pulse inside IF...THEN without changing the condition which activates the if loop ?

Thanks in advance for your time

Would the following achieve the same result, and yes I left out some punctuation.

IF STTESTMEM2 then

     If Not OneShot2 then

          StTestDint - 456

          OneShot2 = True

     Endif

ELSE

     OneSHot2= False

ENDIF
