The grand total don't display at bottom.

 dear all,
I have a summary which sum all the amount on report level, so its out side the group in the data model.

I want to display it at the end of report once per report.

I put it at the end of all items in layout model.

but at run time it changes its position and display on first line disturb the report output.

how to force this to display at the end.
