Thank you very much Linda I am pleased that you understood what I was trying to achieve as I was starting to go crazy over it as I was sure I was doing everything right. Especially considering I have used the over ride system numerous times in the past to change things in both the ZenCart files and mods for that matter.

Thank you for your helpful input it has been very much appreciated. I'm still using version 1.39h on two of my stores due to mods being upgraded to work with 1.5 so I am unable to test to see if this issue is present in 1.5 at the moment.
