Passing Form Variables Between Pages

I am running a test installation of WordPress 1.5 on a PowerBook with Mac OS X 10.3.9, Apache 1.3.33, MySQL 4.1.3 and PHP 5.0.3. I’m using search-engine friendly URLs via an .htaccess file. I have been setting up a new template and everything has been running great so far…

Today I ran into an issue I haven’t been able to find a solution to in any of the forums or via Google and I’m hoping I’m just missing something easy.

I have been taking some of my old PHP pages and importing them into WordPress pages (and cleaning them up for CSS, XHTML, etc.). One of the pages contained a form that passes data to the other page via a post.

My variables seem to be getting lost during the mod_rewrite. Is this a possible reason? Would switching back to the index.php?p=X format fix this problem?

I’d really like to keep the search engine friendly URLs, but I need to pass the data around too…

Any tips greatly appreciated!

Cheers,
