Button id's - firefox and IE different ?

Hi all. I want to have several delete buttons with just one form, and depending on which button is pressed, one of several items is deleted. So I need multiple submit buttons for 1 form, each displaying the same text "Delete" to the user, but each with a different "value" so the PHP script can tell them apart. I've used this code for the buttons... <center><button type="submit" name="btid" value="1">Delete</center> <center><button type="submit" name="btid" value="2">Delete</center> <center><button type="submit" name="btid" value="3">Delete</center> And it works just fine with firefox. But IE does not seem to pass the value back to the btid so when the script asks if $_POST['btid'] == "1" { } the value 1, 2, or 3 is not given back to PHP by IE. It is given back correctly by firefox and works fine. Any suggestions ? Thanks.
