# can a VLookup include "Exclude roll forward if weekend dates returned"

Can an expert resolve this for me.

I am using a VLookup i.e.:

=IF(ISERROR(VLOOKUP(A2,Nov!D:I,6,0)),"",(VLOOKUP(A2,Nov!D:I,6,0)))

But if the date it returns is a weekend I need it to to be rolled forward to the next working day i.e. Monday

so if the date it returns is 27/9/14 I need it to change to 29/9/14

if the date it returns is 28/9/14 I need it to change to 29/9/14

Is this possible

Thanks

Assuming you have Excel 2007 or greater, you can use IFERROR(A1,""), instead of IF(ISERROR(A1),"",A1) - it's quicker.

=IFERROR(VLOOKUP(A2,Nov!D:I,6,0)+CHOOSE(WEEKDAY(VLOOKUP(A2,Nov!D:I,6,0),1),1,0,0,0,0,0,2),"")

Phillip,

sorry to trouble you again on this one but, when the VLookup does it's work, if the field it looks up is blank it is returning 02/01/1900

I thought that IFERROR would stop that?

Thanks & Regards

No, "IFERROR" or "IF(ISERROR" will only return a blank if there is an error.

If column I is nullable, then VLOOKUP will return a zero (instead of a blank value), and you need to check for it:

=IFERROR(if(VLOOKUP(A2,Nov!D:I,6,0)=0,"",VLOOKUP(A2,Nov!D:I,6,0)+CHOOSE(WEEKDAY(VLOOKUP(A2,Nov!D:I,6,0),1),1,0,0,0,0,0,2)),"")

sorry I have another problem now

The date it is looking up is 17/11/2014 which is a Monday but it is returning 19/11/2014

Would you know why?

It isn't for me. Are you sure that there isn't an earlier version of the thing that it is looking up, which has an earlier date?
