Hi Everybody,
I tried to make data validation (dv) to prevent duplicated values in two sheets.
Here is what I need to do: When I put a value in "Sheet1 Column Trx_No" the dv will prevent duplication if its already in Sheet1 or Sheet2 Column Trx_No and also if I tried to put a value in "Sheet2 Column Trx_No" the dv will pops a warning if the value already exist in Sheet2 or Sheet1 Column Trx_No. And I have to keep those two tables separated.
Many Thanks,
topbink
