Or, to redefine the existing range:
Choose InsertNameDefine

I have created data lists that were named (name field left of formula field)
and have those lists tied to cells as drop down data validation options. I
now need to add additional entries to the data lists, but am unable to get
them added into the existing groups. I've tried re-highlighting and naming
again - no go.
I am an admitted novice, but really look forward to getting this recurring
document as drop and click as possible. Appreciate any help.
