dynamic checkboxes - counting how many instances

[bezierstek]

Hi,

I have a form that is created dynamically from database entries, and need to know how many have been checked, but am having problems getting the figure.

The checkboxlist is created using this code

<label>
          <ul>
           <?	
	   $interestsql=mysql_query("select * from interest order by interest");
       while ($interestresult =  mysql_fetch_array($interestsql)){
						?>
                <li>
                   <input name="interestgroup[]" type="checkbox" id="interestgroup[]" value="<? echo $interestresult['intpid'] ?>" />
                <? echo $interestresult['interest'];?> </li>
                 }?>
               </ul>
            </label>

and to check it one the form has been submitted I am using this:

$interestcount =count($_POST["interestgroup"]);
echo "interest count= ".$interestcount;

The form displays fine and the html that is formed by php seems ok, but I always get 0 for $interestcount.

Can anyone help?

Actually, forget that, my silly error.

I actually post to the first page then refresh to the second one which displays the count so nothing was passing to the second page.

Sorted now.
