Can anyone please advise?
I am modifying some code that I was send for a clock timer. The original code activated a solenoid every minute. I have added code to activate a solenoid every second as well. My additional code is towards the bottom, highlighted in yellow. I am using an existing element of code in this, if (WDTticks >= WDticksPerSecond), but get the error that this is undeclared. In the original build, there were no errors.
I have pasted the code below, along with the error. Can anyone guide me as to what Ihave done wrong?
Thank you.
