Error that I can't fix

I have been having this error when I reprogrammed my robot: Error:Undefined variable ‘bStopTasksBetweenModes’. ‘short’ assumed.
Is there anyway to fix it and should I be concerned?

Hi Ryan205,

Unfortunately I am not sure whats causing such error message.
Do you get the message when downloading sample programs as well?
Can you please attach a screenshot of the error message?

Here is a picture of the error.

And when I try to download sample programs, it says No communications link available to VEX device.

The bStopTasksBetweenModes boolean flag is used to allow or restrict user-created tasks from running in between the pre-auton, autonomous, and user-control phases of a VRC match. This is built into the ‘Vex_Competion_Includes.c’ include file that is included in the Competition Template in ROBOTC.

Usually when we see this issue, it is because the Vex_Competition_Includes.c file is not included in the user program properly. To check for this, please paste the entirety of your code (or, preferably, a smaller program that can cause this issue) as a response to this post by using the

 tags.

Here is the code:

#pragma platform(VEX)

//Competition Control and Duration Settings
#pragma competitionControl(Competition)
#pragma autonomousDuration(20)
#pragma userControlDuration(120)

#include "Vex_Competition_Includes.c"   //Main competition background code...do not modify!
