hello all, i'm working on a small project:
I have three checkboxes, when the checkboxes are selected, they show

I have functions for each checkbox each of them show 3 list items when selected using a variable to control them
var counteroftheitem = 3;

<div id="checkbox1">
<li>one item</li>
<li>two item</li>
<li>three item</li>
</div>
<div id="checkbox2">
<li>one item</li>
<li>two item</li>
<li>three item</li>
</div>
<div id="checkbox3">
<li>one item</li>
<li>two item</li>
<li>three item</li>
</div>
the help I need is to create an if statement that will show more items when checkbox 1+2 are selected or 2+3 are selected or 1+3 and if any are selected by themselves

thanks,
