Indra,
thanks for your comment. No sweat. Only 3 steps necessary:
1. Go to the data sheet and insert as many rows as you need somewhere within the existing table, e.g. above row 194. This makes sure that all formulas are using the expanded cell range on the worksheet.
2. Delete the existing data and copy in your own data.
3. Go to the dashboard and increase the maximum of the scrollbar (right click on the scrollbar and choose properties). In my workbook I have 190 data rows. The dashboard table has 15 rows. Thus, my maximum of the scrollbar is 176. You have to change this according to your number of rows.
I hope this will be helpful.
