Why this simple event doesn't work?

I have a sprite, with rotation behavior, and 2 event on the project that's all.

just wanna rotate this red object :

his speed is set:

event are set:

here is what's happen.

on start of preview, works well, the red object rotate on clockwise, then I click button and he invert his rotation, untill now, is ok.

then I click back on a, and object don't rotate. I checked debug, his speed change once, first rotation works, then can't rorate back, still same speed

Replace the second condition "If Speed=-52" with "Else":

If Speed=52 ......

Else ......

Replace the second condition "If Speed=-52" with "Else":

> 
If Speed=52 ......

Else ......

that does not work. still same

It doesn't work because the Speed variable doesn't become -52 when you hit A, you're just telling it to set the behavior speed to Speed 2

Delete the variable speed and speed2, On A Pessed set rotate speed to:

-self.rotate.speed

wooo that's working thank you!
