I'm getting an error message in one of my scripts that is giving me some trouble. It's a random error meaning that it will happen every few times the command is run. It's set in a loop so it will repeat. Sometimes it will even cause the connection between the EZB and computer to cut off. Here'e the error:

Code:

Error on line 25: Missing String Quotes or Invalid Expression at index 14: "

# This Script will return the actual position number of the left catrrage
# #from the Kangaroo withough the 1,p in the begining.
# #Returning feedback with the 1,p causes problems.
# #Do Not Delete. Other scripts depend on this script!
