You are selecting a cell with:
Cells(BlankRow, 1).Select
To copy the value from cell E1 in your other sheet to that cell (modify the range to suit your needs)
Sheets(LeleinValue).Range("E1").Copy ActiveCell
or without selecting
Sheets(LeleinValue).Range("E1").Copy Sheets("Data Form").Range("A65536").End(xlUp).Offset(1)
Unless your sheet name is a variable, I would expect it to be included in quote marks. Is LeleinValue a variable?
Why you are using 65536 rows when there are now over a million rows?
Are you still using Excel 2003?
Range("A65536").End(xlUp)
How about:
Range("A" & Rows.Count).End(xlUp)
or
Range("A1048576").End(xlUp)
