Thanks for your interest. If the solver does not find a feasible solution you need to double check the minimum and maximum amounts you put on ingredients. Also make sure that the constraints in your solver window is correct.
If you go to my TH-cam channel main page there is a link for my Instagram and my LinkedIn profile just on the right side of my picture (on the banner picture). You can contact me through them. I might add a Whatsapp number in the future as well.
Please let me know if you have any questions and feel free to share the videos link with interested people.
