The problem is that the student has two cards, the university card and the ID card, and the numbers are different. I want if he buys with the university number, he does not buy the ID card, and vice versa. The university number, the ID number, and the name are found in the database.

Why does this error appear?

Format of the initialization string does not conform to specification starting at index 0.

You are correct, I am sorry

Do you mean this code?
......................................
Dim adapter3 As New SqlDataAdapter("SELECT BUILDING.Location,Mtype as MealType, " & Textbox7.Text & " FROM TRANSACTIONDETAILS INNER JOIN building on TRANSACTIONDETAILS.Bno=building.Bno WHERE " & Textbox6.Text & " TRANSACTIONDETAILS.TRANSACTIONDATE >= '" & RDate & "' and TRANSACTIONDETAILS.TRANSACTIONDATE <= '" & CCDate & "' GROUP BY BUILDING.Location,Mtype ORDER BY BUILDING.Location", Connection)
Dim ds3 As New DataSet()
adapter3.Fill(ds3, "tran3")
Datagrid2.DataSource = ds3.Tables("tran3").DefaultView
Datagrid2.DataBind()
