Conditional Formatting Formulas

Hi

If you're able to attach a sample file I can take a look.

Most common mistake I find when users have formulas in conditional formatting is the $ signs get mixed up,  or the wrong cells are highlighted when writing the formula.

e.g. highlight all cells that you want the conditional formatting to apply to before writing the conditional format formula and make sure that formula is relevant to the top left corner cell that is highlighted.

Then after applying the formatting click on a different cell and check the formula that is being applied to it via Conditional Formatting > Manage rules.    If the formula isn't referring to the correct cell then start over and change your $ signs.

Having said all this - it could be a totally different reason :)
