problem with DataReport

[nicnat]

I'm using ADO to connect to an access database.On my form I have a textbox dat shows me the field 'samplenumber' in the database.
I have a DataReport and a DataEnvironment
to show al the samplenumbers on a report,
but I have a problem to show only the samplenumber in the report thats in the textbox on the form.
I want to filter the number from the textbox in my datareport.

Can you help please

Thanks.
