How do you protect formulas, but not content?

[LouRob]

Once I have my formulas created; how can I protect the Formula Only, but be able to change the numbers in each formula? Once I get the formula in the cells and I go back to enter the data (numbers) my numbers are over writing my formulas!

Any suggestions?

Thanks in advance -
