Adding onChange to Select box value doesn't do anything

I have this code to add an onChange event to a select control:

catid.attributes['onChange'].value= "FilterByCatID();";
alert(catid.attributes['onChange'].value);

The alert box confirms that the event has been set, but on change of
the selectbox, nothing happens. Any ideas what I'm missing?

Thx.

You've created an "onChange" attribute with a string value, what you
want to do is assign a function to the onchange handler. The most
reliable way is to set it directly:

catid.onchange = FilterByCatID;
Also, it is a convention in javascript that function names starting
with a captial letter are reserved for constructors.
