well, i got something, but it wont work.  No matter what I select, yes or no, it always displays the same response. 

any ideas

if($t27=="1"){
echo "alert('Thank You for Agreeing to Terms & Conditions');";   
// ... checkbox1 has been checked, form processing code here
} else {
  echo "alert('Error! You must agree to the terms and conditions!');history.back(-1);";  // ... checkbox1 has NOT been checked, form processing code here
}

This is the html part of the form

     
                                            Yes
                                            No

if($_POST['input_checkbox_field'] == "on") {

}


checkboxes will post either "on" or "off"  its' weird.

Did this work for you?

I think what is meant is

if($_POST['t27'] == "on") {

echo "alert('Thank You for Agreeing to Terms & Conditions');"; 
// ... checkbox1 has been checked, form processing code here
} else {
  echo "alert('Error! You must agree to the terms and conditions!');history.back(-1);";  // ... checkbox1 has NOT been checked, form processing code here

}

Sorry, Ill try it in the morning.  I just made a text field where the person has to type in yes rather than check it.  Ill try it, I think that would be better than just a text box.

thanks
