Mouse click on object issues

I have been trying to make a simple menu where there are buttons to go to different layouts of the project. I have it set up so that when the buttons are clicked it should take me to the other layout.

Like this:

Mouse -> on left button clicked on (start button): System go to (layout)

When I test the program it doesn't work. When I click the buttons nothing happens.

Any help would be appreciated,

Thanks

Check your (start button) collision polygon. It may be the collision polygon is too not on where you suppose to click.
