Portal sub totals don't always add up

[Mr.Morning]

I have a weird problem. I have a portal that has a listing of prices and taxes for that item. These are simple total items. When I ask for the sum of the totals of prices and taxes I do not always get the correct answer. Somewhere in the process it seems to round off the numbers causing the wrong answer. It doesn't do this all the time which makes solving the problem difficult.

Anyone clues and what to check from anyone would be appreciated.

Thanks in advance,

[Henry]

For calculate the total number in portal, i always set a calculation field and set it as Sum(portalrelated::price). The relationship "portalrelated" is just same as the relationship for use the portal. If you want to round it as 2 digit, you can set it as Sum(Round(portalrelated::price, 2)).
