I recently heard that the autonomous program required a certain template, so I decided to take a look at it. When I opened the program under my sample programs, it said under the errors tab:

**error**: Undefined procedure 'waitforstart'

I was told that wait for start is necessary for the autonomous part of the challenge. Does anyone know why this would happen?

It is waitForStart, not waitforstart. Note: Upper/Lower case is significant in any C languages.

Also, make sure you're calling it like a function. The syntax would be

Sorry, i'm kinda new at this. The line of code I have is copied out of a template for FTC, so I don't know why it won't recognize it. I checked, and it is exactly like you two said it should be.

Would you post your code and the error you got from the compiler?

sure thing, here you go.

and the error message is this:

[spoiler]**Info***:Undefined procedure 'waitForStart'. Global subroutine assumed.
**Error**:Undefined procedure 'waitForStart'[/spoiler]

I have just tested this and it works fine in ROBOTC version 3.54. Double check to make sure your Platform type is set to NXT/TETRIX (not just NXT) and that the Compiler Target is set to Physical Robot; the waitForStart(); command is not supported in Robot Virtual Worlds or the PC Based Emulator and will throw the error you are seeing.

Okay, I checked to see if that was the problem and it turns out that my compiler target was set to virtual worlds. I changed it to physical robot and the command checked out just fine. Thanks for the help!
