I don't really understand what you mean when you say "the brick doesn't do
anything". Can you be more specific?

They will both be executed in sequence if at the time the second if statement
reads the TachoSpeed setting on OUT_L it happens to be below the threshold
setting. If you described exactly what you are trying to make the robot do it
might be easier for both of us to figure out what is going wrong. You may want
to try letting your robot get up to speed outside of your while loop and then
get rid of the 2/10s a second wait and OnFwd call at the start of the while
loop. Perhaps you should make the two if statements into a single if/else
statement instead.
