A cell can contain a formula or a value.

If you type in that value, then you've lost the formula.

Are you saying you want to let the user override the results of the formula, but
not use a different formula?

If yes, then how about an alternative:

Use 3 cells (say A2, B2 and C2):

Put your formula in A2 (with the label Default in A1)
put the label Override in B1
Then use a formula in C2:
=if(b2="",a2,b2)
And put "Use this Value" in C1.

Then lock all your cells and come back and unlock the cells that the users can
type in.

An alternative would be to have an event macro look for a change. If it sees a
value in that cell, then it's ok.

If it sees a formula, it throws it away and plops the original formula into the
cell.

But personally, I like the layout of 3 columns. It's easier to see what's
happening.

Is it possible to lock a formula in Excel so that it cannot be changed, but
still allow the cell content to be changed?
