- I dont know why but I keep getting "undefined symbol" on the LowTime I am just doing what the book has told me to do. can someone help please!. thats for the sumo bot programing.

deetwist, Welcome to the forums!
That error is caused when you do not have a CON statement declaring the LOWTIME constant. I assume you are referring to Applied Robotics with the Sumobot as this code is referenced on page 22. Also on that page is the note to add the CON statement:

√ Add a LowTime constant declaration:
LowTime CON 20

Do you have that in your code as well?

Full code from book:

FYI: It is against the forum rules to double post, so I will remove your other thread with the same question.

And lastly, a tip on posting code on the forums:

Thanks a lot! I am just begining in programmming so Its kinda hard for me to study this area plus I've never had programming background before and english isnt my first dialect so its very hard for me to understand its like Im learning new language!. LOL!... thanks again!
