Hi,
To create the formula, you have to combine IF, AND and OR functions. The following formula is more simple and will give the same result as the one you are using:
=IF(AND(A2>5,B2>5),"OK","NOT OK")
In case of more conditions, it is needed only to add values into AND function. For example:
=IF(AND(A2>5,B2>5,C2>5,D2>5),"OK","NOT OK")
To add OR condition,
you need to include OR function inside AND function. The formula could look like:
=IF(AND(A2>2,OR(B2>5,C2>5)),"OK","NOT OK")
The results will be:
You can also include AND function inside OR function when needed.
