How do I get my enemy to turn left, set mirrored not working

So I am trying to follow the make a platform game tutorial, but for some reason my "set mirrored" to turn the enemy left when hitting the first invisible wall is not working. I have triple-checked what the event sheet says, and it looks correct. Currently for the enemy I have:

Enemy action = "right"-> enemy simulate platform pressing right

sub action: enemy set Not mirrored

Enemy action="left" -> enemy simulate platform pressing left

sub action: enemy set mirrored

Enemy on collision with Edgemarker->

sub event: action="right" -> enemy set action "left"

sub event: else -> enemy set action "right"

Is there something I missed here to make the turning actually works?

Can you send a screenshot of your event sheet?

I tried to post my screen shot, but it is not working....I also tried to post my screen shot from dropbox, got a message that I am not allowed to post urls? not sure how to get the screen shot posted...

Just add a space to the address, to make it seem like it is not an address. People are used to this technique here.

wingzrooke You can use this trick: antiblocklinks|http://www.site.com

You can use any word instead of "antiblocklinks".

And to easily send any screenshot, use Lightshot app for Windows

Okay great, thanks. It seems to be working now, although I'm not certain why the code did not work before and now does...without any changes.

Can you send the .CAPX of your project?
