Check box to validate disclaimer

Good day all,

This is my first post so please be easy. I used code i found on this site to create a check box. I am trying to edit it to redirect the user if the check box is checked after clicking on submit. What is the code for redirect or href?

<SCRIPT>
function Do_it ( ok )
{



if (ok ==false)
{
alert("Please Agree to the Terms");
}
}

</SCRIPT>
