Drop Table Mysql

Trying to drop a table when deleting a user account. Can someone point me to problem?

dim s as string
s= “Farmacia”+selectedrecord+“Prescriptions”
Dim sql As String
sql = “DROP TABLE “+s+”;”

If IsConnected Then

If mDB.Error Then
  textarea1.text="DB Error: " + mDB.ErrorMessage
End If

StatusLabel.Text = "Table deleted!"

MsgBox(“Connect to the database first.”)
End If

What error you get?

No error, I get to StatusLabel.Text = “Table deleted!”

Maybe this ?

If db.Connect Then else end

Sorry, I finally found the error.
The value had not been passed to ‘selectedrecord’
s= “Farmacia”+selectedrecord+“Prescriptions”
