Unused variable about fourth-edition HOT 1 CLOSED

Thanks so much for letting us know! Yes, you're absolutely right—I meant to use guacamolePrice for concatenation. The last line of code in the method should be:

guacamole.Text = "Add guacamole for " + guacamolePrice;

I included the extra variable because some readers are still getting used to the debugger, and I wanted to make it easy for them to see the price if they're debugging through the code.

I'll work with the O'Reilly production team to make sure they're removed from future printings and the digital editions. The update is live on the errata page now: https://www.oreilly.com/catalog/errata.csp?isbn=9781491976708
