Error Message in Forum

Question

I have been having problems when I am on a Proboard Forum. But we have also had problems on other sites.
The biggest one is as follows:
'Postbox.value' is null or not an object. In an error box, asking if I want to debug.. What do I do ??
I can't debug because it's a read only file..
// show smilies in posts
function showSmilies()
var posting = document.getElementsByTagName('input');
for(p=0; p<posting.length; p++)
if(posting[p].type=='submit')
posting[p].onmousedown=function()
post=postBox.value;
for(t=0; t<smCode.length; t++)
post = post.replace(new RegExp(smCode[t],"g"),'[img]'+smilie[t]+'');
postBox.value = post;
}

Not sure, but the second for loop seems unnecessary, since you're only looking for one filename. I'd also reorder the conditions in the first for loop.
var to_del = "F7X Header.eps";
var my_doc = app.activeDocument;
var my_image = my_doc.allGraphics;
for (var i = 0; i < my_image.length; i++) {
     if (my_image[i].itemLink.name === to_del) {
              my_image[i].parent.locked = false;
              my_image[i].remove();
