how to disable other buttons when a button clicked

You're welcome. There's plenty left to learn, so take your time and have fun with it.

Thank you very much!! I obviously am new to all but the simplest Actionscript. I learned that functions go on frames etc.

My app buttons work correctly now.

The function would go in the timeline that has the buttons, not the same layer, just the same timeline where the buttons exist.

The on(release)... code I provided above would be attached to the buttons. To do that, you click on the button itself on the stage, and then enter that code in the actions panel. An alternative that could go where you put the function code is using...

mycase1_btn.onRelease = function(){

// start the movieclip.... whatever you do for that

// disable the buttons
enableBtns(false);

}

The latter may be preferred because it is more readily visible when hunting things down.

The last line... _parent.enableBtns(true);
could be placed in the last frame of the movieclip that is playing (or whatever else might be detecting the end of the movieclip).

I don't know if you missed seeing my reply to your first posting of this, or tried it and couldn't get it to work, but it will work (it's written for your code). If you have a problem getting it to work, just ask for more help with it:

One way to deal with disabling sets of buttons is to have a function that enables/disables them all, as in...

function enableBtns(truefalse){
for(i=1; i<6; i++){
this["mycase"+i+"_btn"].enabled = truefalse;
}
}

Then, within the button functions, you call the function to disable them all along with whatever you do to get the movelip playing...

on(release){.... // depends how you code your buttons

// start the movieclip....

// disable the buttons
enableBtns(false);

}

And when the movieclip finishes playing you need to have the buttons enabled again... which you can have in the last frame of the movieclip.

_parent.enableBtns(true);
