Excel Structured Reference issues

Question

I have 2 separate tables ( FullOrders , ShortedOrders ), each with an [Order Number] column. FullOrders shows every order we've fulfilled and ShortedOrders show only orders that were not sent with all the product.

I've created a column in FullOrders called [Short?] and would like it to show a value of 1 if any ShortedOrders[Order Number] matches the FullOrders[Order Number] that sits on the same row as FullOrders[Short?] . Otherwise FullOrders[Short?] will show 0.

I've tried a few formulas and haven't found the right solution.

Formulas I've tried:

=IF(ShortedOrders[[#Data],[Order Number]]=FullOrder[[#Data],[Order Number]], 1, 0)

=IF(ShortedOrders[[#Headers],[Order Number]]=FullOrder[[#Headers],[Order Number]], 1, 0)

=IF(ShortedOrders[[#Data],[Order Number]]=FullOrder[[#Headers],[Order Number]], 1, 0)

=IF(ShortedOrders[[#Headers],[Order Number]]=FullOrder[[#Data],[Order Number]], 1, 0)

=IF(E2 = ShortedOrders[Order Number], 1, 0)

=IF([Order Number] = ShortedOrders[Order Number], 1, 0)

=IF(E2 = ShortedOrders[[#Data], [Order Number]], 1, 0)

=IF([Order Number] = ShortedOrders[[#Data], [Order Number]], 1, 0)

The results are a 0 for a while, and then #VALUE after it hits the last record in ShortedOrders .

An IF statement may not even be the answer.

Answer 1

I found the answer to this after further research. I needed to nest a COUNTIF for the comparison of the column to the cell.

=IF(COUNTIF(ShortedOrders[[#Data], [Order Number]],[Order Number])>0, 1, 0)
