Script is not working in IE

[pricecd]

Hi guys,

I had a javascript class in school and I can see whats going in the scripts, but I pretty much helpless when it comes to javascript. The code below was written to color the alternate rows of a table. We needed a script because the table data is being pulled from a database. The alternating row color (gray) shows up in FF, but not IE. The code is basic stuff, but I still don't know whats wrong. Hopefully one of you guys can help me out.

		<script type="text/javascript">
		function makeAltRows() {
		var myTable = document.getElementsByTagName('tbody');
		for (i=0; i<myTable.length;i++) {
		var rows = myTable[i].getElementsByTagName('tr');
		for (f=0; f<rows.length;f++) {
		if (!(f % 2)) {
		} else {
		myTable[i].rows[f].setAttribute("style", "background-color:#e5e5e5;");
		}
		
		}
		}
		} // END makeAltRows()
		makeAltRows();
		</script>

this is at the bottom of the page, beneath the table.
