problem when binding matrix data to user form with UDO

hi everybody.....

i have used this syntax for binding database tables...

oDBDataSource = oForm.DataSources.DBDataSources.Add("@My_Table")

this user table is an UDO........

it is saying that "table is not found"....when i run the program

but the same syntax is working when i try to do with database tables like OCRD, AACT..etc...

can u people solve it...
