If the point is to only hide the second set of buttons for short tables, it'd probably just be easier to count the number of rows in the patfunc table rather than try to get at the computed height.

Of course setting the visibility of the second set of buttons is made more difficult because they aren't contained in anything like a table row or div and the number of buttons changes with each form will change. Fortunately, there's JQuery:

<script>
var pfrows = $("div#patron_tables table tr").size();
if (pfrows < 5) {
	$("div#patron_tables span ~ a").hide();
	$("div#patron_tables table ~ a").hide();
};
</script>

We wrap the patfunc token in a div with the ID patron_tables which allows for more precision in the selector. The first selector counts the number of rows in the patfunc table. Then, if that's below a set amount, the next selectors finds all the 'a' tag siblings following the table or span (sometimes the WebPac incorrectly wraps a table in a span) in that div and hides them. It could be that there are other anomalies for the patfunc tables, but I don't have quick access to a patron record that has all of the possible patron function tables. That should be enough to get started, though.

JQuery rules. 

HTH,
David
