Hi!
As per my understanding, you want to show user-defined responses according to the chosen category.
1. Make a dropdown list of category( if you do not know how to create a list then spend 1 minute in
Titlethis article )
2. Then apply the SWITCH function in the output cell (see attached excel file)
=SWITCH(C3,F8,G8,F9,G9,F10,G10,F11,G11,F12,G12)
Where C3= cell containing category list
F8,G8,F9,G9,F10,G10,F11,G11,F12,G12 = cells containing response messages
