Thank you, onkeyup worked.
I have a search form that requires the user to input a six digit code.
There are three tables on the page: Section, Etiology, and Anatomy.
The section and etiology tables are static. However, the anatomy table
must change depending on which section is selected. For example, if
the "Neuro" section digits are keyed then the anatomy table must have
choices for "brain", "head and neck", and "spine". There are 11
different sections, so I need 11 different anatomy tables.
I can't think of another way to do this, but there must be simpler and
more elegant solutions. Any help is appreciated.
