Hello,

Thanks for the question. If I understand what you're looking to do correctly, this can be accomplished using a nested IF formula including the AND and OR functions. More on all of the available functions can be found here (https://help.smartsheet.com/functions), and we also have a blog post on how to build nested IF formulas which can be found here (https://www.smartsheet.com/blog/support-tip-build-nested-IF). Here's an example of how this could be written:

=IF(AND([Column PassFailA]@row = "Pass", [Column PassFailB]@row = "Pass"), 1, IF(AND(OR([Column PassFailA]@row = "Fail", [Column PassFailB]@row = "Fail"), OR([Column PassFailA]@row = "Pass", [Column PassFailB]@row = "Pass")), 0.5, IF(AND([Column PassFailA]@row = "Fail", [Column PassFailB]@row = "Fail"), 0.25)))

For this example I'm also using @row instead of the row's number within the cell reference. This will help make the formula more efficient as this sheet grows larger. More on @row can be found here (https://help.smartsheet.com/articles/2476491#row).

I've also included a screenshot of the outcomes for every scenario you listed. I'd also like to note that if either column is left blank, this formula will leave the % Column blank until both are set to either "Pass" or "Fail".
