Hi
JiffyPark!
I have already explained how you can achieve the same result for X-Cart 5.0 here:
http://forum.x-cart.com/showpost.php?p=370131&postcount=10
The instruction is pretty similar for X-Cart 5.1, but you will have to edit Main.php file of the module and set getMajorVersion to return '5.1' instead of '5.0'.
If I sound complicated to you, please let me know and I will try to help.
Tony.
