Jquery / Javascript scripting to show a div after clicking a checkbox in an iframe

I have a html page which is located at [login to view URL] then i have an iframe inside that page which is located at [login to view URL] then inside that iframe I have another iframe with this code:

<form>

<input type="checkbox" name="c1" onclick="showMe('p1000015037')">Show Hide Checkbox

<script>

function showMe (box) {

var chboxs = [login to view URL]("c1");

var vis = "none";

for(var i=0;i<[login to view URL];i++) {

if(chboxs[i].checked){

vis = "block";

break;

}

}

[login to view URL](box).[login to view URL] = vis;

}

</script>

</form>

I have set the div id p1000015037 to display none but when i click on the checkbox it doesn't work.

I have a working example here - [login to view URL]
