Thank you for the code!

I made a standard deployable module for 5.x that can be uploaded and installed like any other module. I did change the text to "Place My Order".

I hope this helps someone else out. You can edit the text if you want but the code is ready to go and was installed into the production copy after my development.

1) Download the attached file and unzip

2) Then in XCart admin go to Modules and upload it to install. Once enabled the magic should happen.
