i have a table (head) that call "Sell" there is a Sell Nr. Then i have a table with the details "Sell details".
The both tables are linked over the SellNr. In the "Sell details" are two lines and so i have in the column "NR" two numbers. But i only want to calculate when both numbers are in the "Sell details". So i want to say, only when the numbers are in this, then you have to do.... I only have test it with Yes or No to prove if this are in the table.
