Error when importing Access report

Hi! When i'm importing into ReportServer report made with Access i've got those errors:

An error occurred while the report Bank Account Transactions By Type was being imported: Item has already been added. Key in dictionary: '[Bank_x0020_Account_x0020_Transactions_x0020_By_x0020_Type].Parameters![trans type]' Key being added: '[Bank_x0020_Account_x0020_Transactions_x0020_By_x0020_Type].Parameters![trans type]'

An error occurred while the report Bills from Purchase Orders by Supplier was being imported: Item has already been added. Key in dictionary: '[Bills_x0020_from_x0020_Purchase_x0020_Orders_x0020_by_x0020_Supplier].Parameters![vendor]' Key being added: '[Bills_x0020_from_x0020_Purchase_x0020_Orders_x0020_by_x0020_Supplier].Parameters![vendor]'

What is the meaning of those errors? I thought it was because ReportServer was trying to add 2 or more parameter with the same Name but for example in my report Bank Account Transactions By Type i only have one textbox that use the name trans type. So is someone have an idea?

Thanks !
It hapened to me, more or less the same...

For what I know it can be a problem with the default values of the

Report Parameters... they should not be originated by a query.

I had this problem and puting this as static or calculated values solved the issue...

Not the best way as by default the user's are not getting the data shown, but that's a solution.

Hope Microsoft solves the issue.. as this is a serious bug.

Regards,
