I need help getting the value of a checkbox in a form I have. The HTML code for the checkbox is:<br />
<br />
&lt;INPUT TYPE=&quot;CHECKBOX&quot; NAME=&quot;agreement&quot; id=&quot;agreement&quot; VALUE=&quot;iagree&quot;&gt;<br />
<br />
The JavaScript code is:<br />
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var obj15 = document.getElementById(&quot;a<wbr />greement&quot;)<wbr />;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var agreement = obj15.value;<br />
<br />
The PHP code to validate this is:<br />
<br />
$agreement=$_POST['agreeme<wbr />nt'];<br />
if ($agreement==&quot;&quot;)<br />
{<br />
echo 'document.getElementById(&quot;<wbr />emailsent&quot;<wbr />).innerHTM<wbr />L = &quot;You must agree to our Legal Notice and Privacy Statement before submission.&quot;;';<br />
return;<br />
}<br />
<br />
Now, the issue is that I cant get the JavaScript right to get the value of the checkbox. I need some help with this. Thanks. Also, if when you help me, please let me know what the value of false would be, is it an empty string?.... &quot;&quot;&nbsp;? Thanks
