asked on How do I clear drop-down selection so user can make any selection from same drop-down menu?
How do I clear drop-down selection when choice is made so user can immediately make any or same selection from same drop-down (choice made launches new browser window)?
My example URL:
http://www.imshome.com/mdrive23plus_mdi.html#pn
I would like user to be able to easily choose any option from any of 3 drop-downs, whether same option already selected or not. Right now, selection does not clear and selection must be different to launch window with info. JavaScript for this?

Clarified question.
Locate the select element, and change the selectedIndex value to 0

obj.selectedIndex = 0;

HonorGod,
Sorry, I'm not following -
When I change onchange= to onchange="doit(this)" or onchange="doit()", I just get the default messages without sending value to php script. Please see my form tag below (without change above):
(JavaScript function is in head section as given.)
Thank you!

HonorGod,
Yes, having onchange="this.form.submit
But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us. -Romans 5:8 What a glorious God!
