Any advice on how to link input boxes with existing worksheet formulas
would be greatly appreciated.
Thanks!!
First, take a look at data forms - they may be all you need. See "About
using the data form feature for data entry" in XL Help.
A more sophisticated approach would be to use UserForms, which can
incorporate validation, dropdowns, option buttons, checkboxes, etc.,
which can then transfer their data to a worksheet. For foolproof data
entry a UserForm is the way to go.
