=IF(AND(AV14="Yes",ISNUMBER(AV76)),AV76,"N/A")
Thank you for your response and advice, Special-K99. Unfortunately, your solution did not work, either. AV14="Yes", AV76 is not a number, but the response populated with "N/A". If AV14="Yes", the cell should not contain "N/A" regardless of what is in AV76.
Nope, that's impossible.
If you look at the second IF condition, the ISNUMBER() condition, the only possible results for TRUE and FALSE are AV76 or "Hold".
The only way for the result to be N/A is if AV14 is NOT "Yes"
In a blank cell put =(AV14="Yes").
It should say TRUE.
If it says FALSE then AV14 is NOT "Yes" (no matter what it looks like).
(You probably have a space or CHAR(160) after "Yes" - CHAR(160) is common when data has been copied from the web.
If you're still having trouble upload the file to an online storage site and post a link to it so we can examine the data.
