Form submitting field as Blank. Using Javascript to hide and show fields

Question

My problem is that when i fill out this form and submit. It always submits Origin_Radius as empty when i am on origin_city_search div

My hypothisis on the issue is that since i have 2 of the same fields named the same (Origin_Radius) is that it is always taking the value of the last one. in the below form it is the one in the origin_zip_search DIV... witch that radius form works... just not the one in the origin_city_search DIV.

any pointers on how to get this to submit Origin_Radius on each of the divs would be great.

Answer 1

use different names for each field, you can't have 2 fields with the same name, use something like "origin_radius_cs" and "origin_radius_zip"
