Debugging

I am working through Lesson 12 (Debugging Code) and have an issue with the Immediate Window.

I have loaded the Tax Calculator solution and opened the Immediate Window.

When i type in subtotal as the book says, i get "The name 'subtotal' does not exist in the current context". I also tried with a question mark in front.

I thought maybe its because it wasnt running, but it cant be used when running the program.

I also (as suggested) typed sub and pressed CTRL+SPACE and did not get the intellisense help.

Why wont it work. I can see this might be very handy for debugging.

Code:

?subtotal
The name 'subtotal' does not exist in the current context

subtotal
The name 'subtotal' does not exist in the current context

The program does need to be running but it needs to be in break mode so you've interrupted execution. You also need to interrupt execution in a place where subtotal is defined.

Try setting a breakpoint on the line that declares subtotal and then click the Calculate button. That should get you in the debugger where you can do this.
