Using the free app creator tool found at http://appinventor.mit.edu

Write a modular program using block code format done at http://appinventor.mit.edu to create a Bill for an Automobile Repair Shop. The app block code should let the user input a parts amount, the labor hours ($40 per hour), find a subtotal, calculate a 7% tax on the parts only, and make a grand total for the user. It should also clear the boxes when the user clicks the button to make the bill (just before putting the subtotal, tax, and total) or a separate button to just clear the screen. It should have procedures that do the following: ClearText to make the textboxes blank FindLabor it should calculate the Labor Charge as Hours * 40 MakeTotals - Pass this Procedure variables for LaborAmount and Parts (as parameters). It should calculate the subtotal, Tax, and Total and put these values onto the screen The Buttons should do the following: Clear Button Call the ClearText Procedure MakeBill Button Get the Hours and Parts from the screen, Call the FindLabor Procedure [returning the LaborCost or putting it in a global variable is up to you for this one], Call the ClearText Procedure, Call MakeTotals Procedure and pass it the LaborAmount and Parts variables.

*NOTE: I need assistance with coding in Block Code format using the app creator too found at http://appinventor.mit.edu NOT Java Script. The assignment is too use the free App creator tool found at http://appinventor.mit.edu to design and program the app in Block Code format . I have attached new clearer image of what I have so far but am stuck. See attached my Block Code I'm not sure what I''m doing wrong. I need the coding too be in this format so that I can understand what I am doing wrong. This was completed using the free app creator tool found at http://appinventor.mit.edu Please provide assistance with coding the Block Code using the free App creator tool which can be found at http://appinventor.mit.edu NOT Java Script
