lock cells

[novice]

Can I lock a condition alone in a cell so that the cell still can be modified

Example

in A1 I have a drop down list (select A, B ,C)
n B1 I have IF(A1="A","Ape",IF*(A1="B", "Banana",if(C1="","")))
How do I protect C1 from being deleted when users fill in the form?

One guess hazarded .. perhaps you're asking this ? You can have cells
containing formulas locked against accidental erasure / overwriting.

If say, only col C contains formulas that's to be protected, then try this
sequence. Select the entire sheet, click Format > Cells > Protection tab >
Uncheck "Locked" > OK. Then select only col C, click Format > Cells >
Protection tab > Check "Locked" > OK. Then apply sheet protection via
clicking Tools > Protection > Protect Sheet > Password? > OK. That's it.
Test it out. Only col C would be protected. Elsewhere on the sheet, cells
would be unprotected, allowing for say, data inputs.

Glad that turned out fine for you !
