Hi,

I have a contact form that email on submission, is there a way I can add something to my code to make the "terms & conditions" tick box mandatory so you HAVE to tick it before the submit button can be pressed?

Cheers

Is that a question? or an anounce?

Well the fact that there is a "question mark" at the end of the sentance would point to a.. erm... question?

But in fairness, I DID forget to post the code so I'll let you off with that (unless your a bot...?)

<form name=terms form  method="POST" action="payment-text-link.php">
			    <table width="500" border="0" cellspacing="3" cellpadding="3">
                  <tr>
                    <td width="108">Name:</td>
                    <td width="392"><input type="text" name="Name" /></td>
                  </tr>
                  <tr>
                    <td>BusinessName:</td>
                    <td><input type="text" name="BusinessName" /></td>
                  </tr>
                  <tr>
                    <td>BusinessAddress:</td>
                    <td><textarea name="BusinessAddress" rows="5"></textarea></td>
                  </tr>
                  <tr>
                    <td>Telephone:</td>
                    <td><input type="text" name="Telephone" /></td>
                  </tr>
                  <tr>
                    <td>Email:</td>
                    <td><input type="text" name="Email" /></td>
                  </tr>
                  <tr>
                    <td>Website:</td>
                    <td><input type="text" name="Website" /></td>
                  </tr>
                  <tr>
                    <td>BusinessAdvert:</td>
                    <td><textarea name="BusinessAdvert" cols="50" rows="10"></textarea></td>
                  </tr>
                  <tr>
                    <td>&nbsp;</td>
                    <td><input type="checkbox" name="CHKBOX_1" value="yes"></p>
                    
                      <span class="style13">* I have read the terms &amp; conditions of buying this link
                      &nbsp;</span></td>
                  </tr>
                  <tr>
                    <td>&nbsp;</td>
                    <td><input type="submit" name="submit" value="Continue To Payment Page" /></td>
                  </tr>
                </table>

Here's a quick and dirty way to do it. I usually don't advocate inline scripts like this, but it will still teach you something:

<tr>
<td>&nbsp;</td>
<td><input type="checkbox" name="CHKBOX_1" value="yes" onclick="if(this.checked){document.getElementById('submit').disabled = false;}else{document.getElementById('submit').disabled = true;}"></p>

  <span class="style13">* I have read the terms &amp; conditions of buying this link
  &nbsp;</span></td>
</tr>
<tr>
<td>&nbsp;</td>
<td><input type="submit" id="submit" name="submit" value="Continue To Payment Page" disabled="disabled" /></td>
</tr>

Note that I put an id="submit" on your submit button, as well as making it disabled by default.

Cheers Abel!

Thats solved it in an even better way than I thought it could be done!

If it's important legally for them to check the box, you may want to consider validating it on the server once it has been submitted, however, since JavaScript is client side stuff and could be bypassed.
