Hello,
I am new to robotics and just purchased the QTI line Follower AppKit for the Boe-Bot (#28108) the source code that came with it generates the following error message:
·Error 129 - Expected ':" or End-of-Line. This message occurs when the program gets to the "qti" text immediatly after the SELECT text. I have included the program below and colored the text red where the problem seems to occur. Can you help???
Thanks
