Please help.

I have a column I want to copy to another sheet. I just click the column
and copy there are 20738 rows.
Then I go to the next sheet and try to paste. I click the first cell in the
column, then with the shift and down arrow I go to row 20738.

I keep getting this error. There are the same number of cells.

Is there a simpler way to get to row 20738 than the down arrow or going to
the row and clicking.

anyway, how do I get rid of this error?

tia,
