help on keeping an variable value coming from the url on.

[co.ador]

I am using a form in page 1.

 

When I fill the form and click summit it passes several variable values pickup  in page 2, page 2 uses a pagination script and the first time it display the data coming from the form, displaying the values but when i click in the second page in the pagination rows of numbers then the variable coming from page 1 to page 2 turns off only for the query of the three used in the script below WHERE (zip= '$strZipCode') on the very top of the script right below where zip=$strZipCode variable coming from page 1 form is extracted. in this case the variable $strZipCode will activate the query below so, if that variable value is not through then the query won't display it's fields zip, state etc... It does = to false when users goes through pagination in page 2. It seems like the value of $strZipCode is lost. How can I still maintain the variable value through pagination?

 

what is happening in this query that the variable $strZipCode is not passing true when users paginate through when looking for more set of rows results?

Have decided to post the code again since it was very hard to read in the first post.

Firstly, this is not allowed

Hopefully you've just edited out some code and not remembered to delete one of those

As for the problem you're having, why not save the value in a session variable?

that was a typo...
