counting check boxes

Hi, I have run into a little problem, its hard to explain so am giving you the whole code below: I am getting a string to countchecks.php which is like: countchecks.php?id=154&id=198&id=505&id=809&id=1100 taking that I have to format it into select * from asdf where id=154 and id=198 and id=505 and id=809 and id=1100; How can i do that? Below is the form that i am using... (to make the code easy to read i renamed "checkbox" to "id" above) <form name="form1" method="get" action="countchecks.php"> <table width="71%" border="1" cellspacing="2" cellpadding="1"> <tr> <td width="20%"><input type="checkbox" name="checkbox" value="154"></td> <td width="80%">154</td> </tr> <tr> <td><input name="checkbox" type="checkbox" id="checkbox" value="198"></td> <td>198</td> </tr> <tr> <td><input name="checkbox" type="checkbox" id="checkbox" value="202"></td> <td>202</td> </tr> <tr> <td><input name="checkbox" type="checkbox" id="checkbox" value="505"></td> <td>505</td> </tr> <tr> <td><input name="checkbox" type="checkbox" id="checkbox" value="809"></td> <td>809</td> </tr> <tr> <td><input name="checkbox" type="checkbox" id="checkbox" value="1100"></td> <td>1100</td> </tr> <tr> <td><input type="submit" name="Submit" value="Submit form"></td> <td>&nbsp;</td> </tr> </table></form> Kindly help.
