onClick not responsive... I'm going to lose it

[Adelyra]

Hello!!

I can't, for the life of me, figure out why this code is unresponsive. When I first wrote it it worked once, then never again. Here it is:

Embeded javascript (in head tag):

<script type="text/javascript">

function deleteConfirm(){

    var confirmDel = confirm("Are you sure you want to delete this image?");

    if(confirmDel){
         //Continue to edit.php
    }else{
         return false;
    }

}
</script>

HTML:

<form name="deleteForm" id="deleteForm" method="post" action="edit.php">

     <input type="submit" name="btnDelete" id="btnDelete" title="Delete Image" value="X" onClick="return deleteConfirm()" />

</form>

So, I've tried everything I can think to fix this but for some reason it just doesn't do anything. Even if I replace the confirm script with a simple alert: nothing. I added window.onload = function(){ alert("Hello"); } and that worked just fine.

For the actual onClick script I've done onClick, onclick, added a ';' at the end of the brackets...
