I have built some charts in pptx (with ThinkCell) based on an Excel-Sheet (separate document). Now I want to create a field in pptx (I guess with VBA) where I can enter a value (in my case a growth rate) and that value is then used in a certain cell in the Excel-document. How do I create such a field in pptx and link it to my excel?
To put it in other words, I need a field where I enter a growth rate in pptx, it runs the calculations in Excel and then displays me the graphs again in pptx again (displaying of graphs already working).
Thanks a lot!
