If B15 contains "1950-12-20" in text, and D15 contains: =IF(OR(ISERROR(AND(MOD(VALUE((LEFT(B15,4))),4)=0,MOD(VALUE((LEFT(B15,4)) ),100)<>0)),ISRROR(MOD(VALUE((LEFT(B15,4))),400)=0)),"Y","N") Does anyone see my mistake, the error? It currently evaluates to #NAME? error, and I didn't want that. Basically, I am trying to it to tell me if the year is indeed a leap year. I discussed this before, and I thought this was the formula suggested to me. I wrote it out on paper, hoping the error would jump at me, but gracious, I do not see it. Even if B15 were to contain "????-08-30" I would not want that "#NAME?" I would prefer it display a simple "N". Thank you.
