Sam,
your code looks correct. Just to be sure I converted old 'two grids on one page' example and it works fine as well - here is the complete code
<html>
<head>
<title>ActiveWidgets Grid :: Examples</title>
<style> body, html {font: menu; background: threedface;} </style>
<link href="../../runtime/styles/classic/aw.css" rel="stylesheet" type="text/css" ></link>
<script src="../../runtime/lib/aw.js"></script>
<style>
#grid1 {height: 200px; width: 100%; border: 2px inset; background: white}
#grid2 {height: 100px; width: 100%; border: 2px inset; background: white}
#grid1 .aw-column-1 {width: 200px; background-color: threedlightshadow;}
#grid2 .aw-column-1 {width: 150px; background-color: infobackground;}
.aw-column-2 {text-align: right;}
.aw-column-3 {text-align: right;}
.aw-column-4 {text-align: right;}
.aw-grid-row {border-bottom: 1px solid threedlightshadow;}
.aw-grid-cell {border-right: 1px solid threedlightshadow;}
</style>

<p>
Here is the first grid:
</p>
<script>
var obj1 = new AW.UI.Grid;
obj1.setId("grid1");
obj1.setRowCount(15);
obj1.setColumnCount(5);
obj1.setCellText(function(c, r){return data1[r][c]});
obj1.setHeaderText(function(c){return columns1[c]});
document.write(obj1);
</script>
<p>
And another one...
</p>
<script>
var obj2 = new AW.UI.Grid;
obj2.setId("grid2");
obj2.setRowCount(5);
obj2.setColumnCount(5);
obj2.setCellText(function(c, r){return data2[r][c]});
obj2.setHeaderText(function(c){return columns2[c]});
document.write(obj2);
</script>
</body>
</html>
