I have attempted to add the formula by clicking on the line items as opposed to copying and pasting & I am getting the same error message.
However, I did notice something on my Model that was a little different then the model in 9.2.5 Activity: Add Formulas to Price Growth Rates Staging Module.
In my SYS06 Product Details module, the product family shows as "CH" and in the Lesson 9.25 module is shows as "Chocolate". Could this possibly be the reason for my error message? If so may you please advise how I can fix my module to match the Lesson 9.25. I attempted to do this on my own by going back to the earlier lessons but could not figure it out.
Please see screenshots for your reference & thank you in advanced!
