Visual Basic Question?

I've been working on this project for over a week now and really need help on a couple things. I'm wanting to display the amount input into NumberPiecesTextBox into TotalNumberLabel. Thinking TotalNumberLabel.Text = Val(NumberPiecesTextBox.Text). Not working though. Also Have decimal values pulling from igned constants dependent on a number input into a textbox. I am wanting to display the value of the selected constant in AverageLabel as text. ex Const SCALE_A = .50 Const SCALE_B = .60. So how would I make a value of one of those constants display in the AverageLabel.Any help much appreciated, I have a CISCO Final and can't put too much more time into this project. Thank You!
