I am a beginner using Visual Studio (Basic) for my coding program. This exercise is from "Microsoft Visual Basic 2015 RELOADED" book, Chapter 10, exercise #26, page 544.

Here is the exercise:

Open the Tax Solution (Tax Solution.sln) file contained in the VbReloaded2015\ Chap10\Tax Solution folder. The interface provides a text box and a combo box for entering a sales amount and a tax rate, respectively. The calcButton_Click procedure should remove the percent sign and the space that precedes it from the tax rate before using the rate to calculate the sales tax. Finish coding the procedure. Save the solution and then start the application. Close the solution. (1, 6)

Here is the existing code:

Here is the Interface:

The box to the right of "Tax rate:" is a ComboBox with rates 2% To 10% Step 0.005 The box to the right of "Sales:" is a TextBox. The box to the right of "Sales tax:" is a Label.

All the Options need to stay as is. I believe all that needs to be worked out are LINES 42 - 51 (lines with comments and no code). Thank you so much for your help and work! And again I am a beginner at this using Visual Basic.
