ActionScript 3.0 :: How To Get Six Cards Each With Own Numeric Value

What it is I am trying to achieve is 6 cards each with their own numeric value. (1, 2, 4, 8, 16, 32) when the card is clicked its values get added together and but remain invisible until the reveal button is pressed.

ActionScript Code:
c1_btn.addEventListener(MouseEvent.CLICK, c1Click);
c2_btn.addEventListener(MouseEvent.CLICK, c2Click);
c4_btn.addEventListener(MouseEvent.CLICK, c4Click);
c8_btn.addEventListener(MouseEvent.CLICK, c8Click);
c16_btn.addEventListener(MouseEvent.CLICK, c16Click);
c32_btn.addEventListener(MouseEvent.CLICK, c32Click);
reveal_btn.addEventListener(MouseEvent.CLICK, revClick);
[Code] .....

I tried to utilize a basic calculator script and tryed to modify it. This is probably the the 5th version iv made.
