Yes, I was looking at that. How you have it is not how it actually is.

You will need to determine why your browser is intentionally messing up the code. The code everyone else gets is:

function openInvoice(URL)
{
var load = window.open(URL,'','scrollbars=yes, menubar=no,height=470,width=740,resizable=no,toolbar=no,location=no,status=no');
}

It seems to work now! What i did was :

In Chrome go to advanced settings and scroll down to the last option :
Reset browser settings to default.

I don't know why it worked because i've never messed with these settings before.

I hope this helps anyone else that may have the same problem.

And many thanks to you Burn i don't think i could have solved this on my own
