Private Sub btnCalc Click sender As Object, e As EventArgs Handles btnCalc. Click calculates and displays the number of gallons in a pool and the number of ounces of clarifier needed Dim pool As New Rectangular Pool Dim Gallons As Double Dim dblounces As Double Double .Try ParseCtxtLength Text, pool.

ToString "NO") lbiclarifier. Text db10unces. ToString "N1") End Sub

Explanation / Answer

If the defintion of the class was provided then it would have been better, however I am assuming that RectangularPool is a class with some method as GetGallons. Now, in order to access a method outside of its class, you have to use the period operator followed by parentheses (). Your program here is missing the parenthesis. Let me know after inserting the parentheses, you get an error or not.
