I'm sure I checked there and that file wasn't there at the time. I must be going mad. Thanks for the link anyway.
After having read the How to I realise that I had actually done what I needed to do correctly. Which means the progress bar isn't working. Can I ask, is there a file other than the file within which DFP is being used that needs to be uploaded? I had this problem with DFP itself where there was a whole file that I didn't know about that needed to go. I really think this sort of information is critical and should be in the How To's. I only update the relevant file rather than my whole website because their are just too many differing files to sort through. If I don't know what other file to upload then I'm stuck.
can't send you a link because it is in a secure area of a secure website which would require registering etc etc.
