passing a parameter to fillby

I am trying to dynamically populate a binding navigator with selected pieces of a dataset that occur in real time.

The fillby statement is:

SELECT        record_item, category, item_date, data_item_1, data_item_2, data_item_3, data_item_4, data_item_5, picture_name, ID
FROM            records
WHERE        (category = '@mycategory')
ORDER BY record_item

category is a string variable

my fillby statement is as follows:

 Me.RecordsTableAdapter.FillBy(Me.ContactsDataSet.records, ComboBoxCategory.Text)

the error is:

“too many arguments to ‘public  override  Overloads function fillby(data Table as ContactsDataSet.recordsDataTable) as integer’

I am using VB 2012.  I cannot see what I am doing wrong.

Suggestions?
