http://dev.etkinllc.com.gamma.reol.net/availabilities.php

question is:
when the user chooses something from the dropdown, and then clicks on the property, it leads them to another page...
now when they use the BACK browser button, i get the message, "The page you are trying to view contains POSTDATA that has expired from the cache.."

how can i rid of this popup alert??

i would also like it to lead back to their previous query and keep those results there.

any help would be appreciated... ill post the code of the site

For remembering the data submitted, try using this script (javascript) http://javascriptkit.com/script/script2/rememberinput.shtml

As for the post data, there are 3 options that I can think of. The first would be to use sessions, the second would be to have the links to the properties open in new windows, and the third would be to have a frame that overlays on the page with the properties inside of it.

For the first option - I have no clue how to do it, I just know of it.

For the second option - simple, target="_blank" or target="_new" should do it.

For the third option - it's the same effect as the lightbox. What lightbox does is, once incorporated into a tag and clicked on, shadows the whole page with what you want on top. Then, once a link is clicked to close the frame that was loaded, it reverts back to the original page. (See http://www.huddletogether.com/projects/lightbox/ with the 'Lightbox Gone Wild' mod or the 'Leightbox' mod.)

Personally, I would go with the third option. It looks interesting, it entices the visitors, and it gives a professional look with minimal effort.
