You might notice that the Accepted Ask Amount value on a constituent's Fundraiser tab > Opportunities and Asks subtab has a different amount shown than the sum total of the values contained on the "drill-through" page (clicking the Accepted hyperlink value to go to the Opportunities page for the Fundraiser).
We are currently evaluating this issue for a fix in a future service pack.
