form with check boxes

Pavlos1316

[FONT="Times New Roman"]Hi to all (quite new still)

I have a form with checkboxes. It works fine.
It has 24 columns. 8 rows X 3 colums each.

I need when the form is submited to check if:

every row has at least 1 column checked
there are no more than 9 columns checked.

That means one column checked in every row exept one that will have 2 columns checked.

Can anyone help me? 😕

Thanks [/COLOR][/SIZE][/FONT]

How have you named the checkboxes, what system have you used? Something like name[row][col]?

Also.. Please post in normal colors

This is the code for one of my checkboxes
For the rest I just repeat the code.

<body>
<form id="form1" name="form1" method="post" action="ccc.php" target="_self">
  <p>&nbsp;</p>  <table width="352" border="1" align="center">
    <tr> 
     <th colspan="4" scope="row">
<span class="style7">bbb</span>
</th>
    </tr>
    <input type="checkbox" name="a" id="a" value="a" />
        -</span>
        <input type="checkbox" name="b" id="b" value="b" />
        <span class="style3">
- </span>
        <input type="checkbox" name="c" id="c" value="c" /> 
</span></td>
