Help Again with FFVI

[Summoner Yuna]

So, I'm up to Vargas and I fight him and Sabin shows up. I do the Blitz Command and push left, right, left and then X to confirm (I'm playing PS version) but the only message I get is Incorrect Blitz Input. I don't know what else to do. I know I'm supposed to use Pummel but that's the only message I get. Am I doing something wrong? Could it be a glitch in my game? Because just before fighting Vargas the screen went all weird. So thanks to anyone who answers this.

Maybe you hit the buttons too fast? Have you tried to repeat it at a slower speed?

I think you have to hit X first to confirm that you're going to input the Blitz first...I forget. Try inputting the Blitz again after you hit X, maybe...

Select Blitz with X, then input Pummel which is left, right, left.
So press them, it might help if you slide your thumb, which you'll need to do later for diagonal commands. Then after LRL press X. Sabin should use pummel, if he doesn't I suspect there is something wrong with the game. So maybe reset and try again. Anyway you don't need Blitz to beat Vargas.
