A very good morning to you, Adrien!
I've purchased another extension from you as they're all extremely beneficial to our shop's functionality and your brilliant support is second to none! Once I've moved from development to production mode when I'll have more time, I'll be sure to write up testimonials for each and every one of them.
Anyhow, enough of the plaudits, let's get down to brass tacks.
I've set up this nifty plugin to show on product pages of three test products. I've been testing this and what it's currently doing is adding the input amount to the total. I'll keep testing in the hope that I uncover a config error of my own doing but meanwhile if you have an easy solution for fixing this issue, I would be very grateful for your help.
Use your Super User credentials to log in and see the plugin in action of the following three products:
