I have two sheets of data and Column A on both sheets has the same
type data (numbers) some numbers are the same on both sheets in Column
A, some are different, the numbers are not in the same order on both
sheets. Sheet1 also has a value in Columns Q & R in the same row that
is associated with Column A. I want to copy the value in Column Q&R
to Sheet 2 if the same number in column A exists on sheet 2. Can
anyone help me with this?
