Hello there,
I reviewed the spreadsheet you shared and would like to inform you that we are working on very similar requirements for other games (Hockey, Football, Baseball etc.) to put their models up on wordpress sites.
In some cases we are developing the wordpress sites from scratch and in others we are doing modifications to the existing sites.
If I understand your requirement correctly, the calculator needs to be integrated with the page you mentioned and user would be able to enter the values in a column (equivalent to column B in your sheet) and will see the grid (grey cells) and result (THIS) on the grid.
I am assuming the formulas are fixed and do not change (at least frequently). Right?
I can create the plugin as required.
Please drop a message to me if you would like me to work on this project for you and we may discuss the next steps.
Look forward to hear from you and thank you for considering my bid
Best Regards,
Rishi
