Multiple List Box form to build dynamic query feedback wanted

[starace]

I have designed a form that has 5 different list boxes where the
selections within each are used as criteria in building a dynamic
query. Some boxes are set for multiple selections but these list boxes
do not necessarily need to have a selection made to be used in the
dynamic query.

In essence the form can have selections made in all or none of its list
boxes to form the dynamic query

I am looking to get some feedback in reference to my code. I am in no
way an expert and am always looking for some helpful hints to improve.

The following code is lenghty and complex and am sure can be condensed
and improved. If you got nothing else to do or are good natured enough
to help an inquiring mind I would appreciate some feedback.

Thanks in advance
