I have two columns: A & B. Assume A contains a combinaton of numbers and
letters (e.g. 13.00.10i.022) and is formated as "General." Column B is a
whole number between 1 and 3. I would like to create a Conditional Format
formula that says "IF B=1 AND A does NOT begin with the number "12", then
color that ROW red. Continuing, "IF B=1 AND A DOES begin with the number
"12," then do nothing (no color format). How do I do this?

Thanks !
