Activate / De-Activate Layers and/or Groups

[peejaygee]

HI All, I'm turning here for help.

When I started my game, I had 4 Frames.

Title
MainLevel
GameOver/HighScore
Shop

and I would jump around as needed.

I had a thought about the ability to activate and de-activate groups of events, so I figured I'd try to change things, so the frames were not needed.

I have all the groups (apart from Title) de-activated in the event editor, and I have the beginning of the frame using a 1 * fastloop, making sure at tunrtime the 3 groups I don't need are de-activated.

Then I have it, so, if you click on a button on the Title, it 'should' activate 'MainLevel' hence on the event loop, it will now get to 'MainLevel' and on 'MainLevel' I have de-activate 'Title'

So in theory, it should loop the 'Title' until I click the button, then activate 'MainLevel' which inturn de-activates 'Title' and then loop around 'MainLevel' group of events.

But it's not working.

I don't know if I'm missing something obvsious, or what? I've tried finding a way of 'De-activating' layers, but I don't think that is possible.

Can anybody point me in the right direction?
Regards
