Variable Issues Using A Form

[fleabel]

I have a little form with two drop down menus. These two selections are used to pull required information from a flat file database. I have then integrated a piece of script that sorts the columns. This all works beautifully if I bipass the form and just hard code the two variables, however, if I use the form to set the varibles it works great to get the initial information but as soon as i try to sort it the info disappears. I have enough sense to know that this is because it is 'loosing' the varibles from the form but I have absolutely no idea how to fix it.

I think the problem has something to do with the page being reloaded when you click on the header of the comlumn you want to sort by. But I could be completely off track.

If someone can save me that would be much appriated [img src=\"style_emoticons/[#EMO_DIR#]/smile.gif\" style=\"vertical-align:middle\" emoid=\":smile:\" border=\"0\" alt=\"smile.gif\" /]

you should use the $_GET method to pass on the information you are looking at, the _POST variables are lost otherwise
