single checkbox enable/disable dropdown

Kevin

I've been looking all over and I can't seem to find what ought to be
simple.

I need to disable a drop down when a checkbox is checked, and enable it
when same checkbox is unchecked.

I've found any number of scripts to disable / enable a drop down but they
are all made to work with 2 different buttons, radio group selections, etc.
I can't seem to come up with one that can toggle off a single checkbox.

help please.

Thanks
