What kind of variables were you looking to have?

can you post the code of the page where the iframe is?
maybe you are accessing the iframe before it is even loaded.

well there's hardly anything coz i just started it.

<head>
<script src="bombgame.js"></script>
</head>
<body>
<center>
<iframe src="iframe.htm" name="gamescreen" style="width:85%; height:90%; border:2px solid; border-color:gray" frameborder="0" scrolling="no"></iframe>
<BR>
<input type="button" value="Start!" onclick="this.blur()">
</center>
</body>

the code that was supposed to start like a nice little, well-behaved code on the bombgame.js page was this:

top.totalbombs=10
top.bps=2
top.bombno=0

//the next two lines are the problem

gamescreen=top.frames["gamescreen"]
gamescreen.bombid=[]

actually the whole game was showing signs of working pretty well, on a single page, before i changed my mind and wanted it in an iframe within a page, and started all over again.

i was correct! you accessed the iframe before it was even loaded.

<head>
<script src="bombgame.js"></script>
</head>
<body>
<center>
<iframe src="iframe.htm" name="gamescreen" style="width:85%; height:90%; border:2px solid; border-color:gray" frameborder="0" scrolling="no"></iframe>
<BR>
<input type="button" value="Start!" onclick="this.blur()">
</center>
</body>

once the bombgame.js is loaded, it will execute the code inside it but the iframe hasn't been loaded yet.

the solution is, put the codes in a function and call it onload
