Need Support with Index Match and If Function

Hi,

Let's suppose that the all possible values in column B are as follows:

• 289C
• 389C
• 489C

And if the value is 289C, then add 1 day to the date resulted by the formula, but if the value is 389C, then add 2 days, and if the value is 489C, then add 3 days.

If so, please try to update the formula as follows:

=IF(B2="289C",
IF(X2="D",(IF(AND(Z2="Z999",Y2="Ready For Payment"),INDEX(Calendar!E:E,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)), Calendar!E:E,-1)),(IF(AND(AB2="Wkly",Y2="Ready For Payment"),INDEX(Calendar!E:E,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)), Calendar!E:E,-1)),(IF(AND(U2="MP",Y2="Ready For Payment"),INDEX(Calendar!C:C,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)),Calendar!C:C,-1)),(IF(AND(U2<>"MP",Y2="Ready For Payment"),INDEX(Calendar!E:E,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)),Calendar!E:E,-1)),"")))))))),(IF(X2="F",(IF(AND(Z2="Z999",Y2="Ready For Payment"),INDEX(Calendar!F:F,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)), Calendar!F:F,-1)),(IF(AND(AB2="Wkly",Y2="Ready For Payment"),INDEX(Calendar!F:F,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)), Calendar!F:F,-1)),(IF(AND(U2="MP",Y2="Ready For Payment"),INDEX(Calendar!D:D,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)),Calendar!D:D,-1)),(IF(AND(U2<>"MP",Y2="Ready For Payment"),INDEX(Calendar!F:F,MATCH((IF(N2<TODAY(),TODAY()+1,N2+1)),Calendar!F:F,-1)),"")))))))),"")))
