What does Filename must match clock ID error mean?

To ensure the correct files are used when uploading ads into Peach Connect the file name must match the ID. 

This is the unique code for the ad. In the UK this is referred to as the Clock ID, in France the Pub ID, in Germany the Motif Number etc etc

If the file name does to match the upload will not start.

Depending on what is correct either the ad details in Peach Connect will need to be edited or the file will need to be renamed.
