Pinata pricing

You sell three different types of pinatas. Pandas cost $14 each, lambs cost $12 each, and bunnies cost $9 each. Write a program that computes the total price of an order.

Here's a sample:

The program validates the three input fields. They should all be numbers zero or more. If any of them is bad, show one error message, like this:

Don't create your own workbook. Download this one instead. It has some code already there:

1. Private Sub cmdRun_Click()
2.     Dim pandas As Integer
3.     Dim lambs As Integer
4.     Dim bunnies As Integer
5.     Dim inputOK As Boolean
6.     Dim totalPrice As Integer
8.     'Input
9.     getInputs pandas, lambs, bunnies, inputOK
10.     If Not inputOK Then
11.         'There was a problem with the input.
12.         End
13.     End If
15.     'Compute the total price.
16.     computePrice pandas, lambs, bunnies, totalPrice
18.     'Output the total prie.
19.     outputPrice totalPrice
21. End Sub

Don't change this code! Don't add or remove anything. Your job is to write the Subs. All the usual coding standards apply.
