Here is a strange thing that somebody asked me and I couldn't find an answer.

We have a sheet where there are a lot of formulas and they are in locked
protected cells. The user fills in other unprotected cells.

Sometimes the user puts in a value and then realizes that it is in the wrong
place so they cut and past it into the correct place. When they do this it
alters the formula that was using the cell.

Example:

b2=if(upper(a2)="Y","Yes","No")
user puts "Y" into A2 then cuts it and pastes into Sheet2.A1
b2 becomes:
b2=if(upper(sheet2!a1)="Y","Yes","No")

Is there anyway to keep B2 from being changed?
