Problems with resizing an image's width

[Retrobolt]

I want the player to be able to resize an image's width with a add and subtract button.I figured out how to do it,but it only does it on one side.Does anyone know how to make it work on both sides or could you tell me a alternate way to do it.
Also how can I make a button repeat while pressed.Thank you

Heres the mfa-

I'm sure there are better solutions yet here's a start

Thanks for the example,I did find a better solution.
Mouse is over button
repeat while left key is pressed

These attached thumbnails suck there too small and low quality.
Is there a better way to show images?

Retrobolt you could upload the image to google drive or something and post a link

Looks like the same solution to me. I wasn't aware you needed it for Keyboard, glad it's working better
