Programming trouble

Hi everyone. I am a green horn to all this so be gentle. I am working on the BOE kit and activity #5 the reaction timer. I wrote the program just like it is in the book but I am coming up with error 141. Here is what it all looks like. The error is happening at the 1st "DO" and then if I delete it hits the next one. Anyone have an idea for me?? 
Thank you for all your help.
