Hi,
I use a function like the one below to test for a subform containing empty fields, so you could pass in the subform and if you get a true response set the presence property of the subform to "hidden".
function isNull(node)
{
//Debug.trace(arguments);
var result = true;
switch (node.className)
{
case "exclGroup":
case "field":
result = node.isNull;
break;
}
for (var i=0; i<node.nodes.length && result; i++)
{
var childNode = node.nodes.item(i);
if (childNode.isContainer && childNode.className !== "draw" && childNode.className !== "variables")
{
result = isNull(childNode);
}
}
return result
}
Depending on how complicated your subform is it might just be simplier to test the fields individually.
