Formula to auto fill date based on last non blank

Jeeppler

I figured out the formula to give me exactly what I need in Excel:

=IF(LOOKUP(2,1/(A1:D1<>""),A1:D1),EOMONTH(LOOKUP(2,1/(A1:D1<>""),A1:D1),3))

 

This formula does not translate to smartsheet. I need a formula that finds the last non blank in the row and auto fills a due date of 3 months later, last day of the month.

 

 

L_123

=DATE(YEAR(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)), MONTH(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)), DAY(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)))

Was working on this and realized I have somewhere to be so here is what I came up with. This grabs the Date of the correct cell. 

 

=INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)

This grabs the last non-blank and separates into Day Month and Year Values.

=DATE(YEAR(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)), MONTH(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)), DAY(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)))

This is turning up #unparseable for me

L_123

=MONTH(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)) + "/" + DAY(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1)) + "/" + YEAR(INDEX(A2:F2, 1, MATCH("", A2:F2) - 1))

 

Posts the cell you are looking for in Month/Day/Year
