Hello Rajeev,
Not sure which motor kids are using to check for rotations in ‘follow tape’ myblock.  Whichever motor is used, that motor has to be RESET before the loop starts to ‘follow tape’.
Your first ‘follow tape’ might be working as more rotations are provided than what is needed. The second time it doesn’t work as it already exceeded that many number of rotations.

Hope this helps.

Thanks,
Madhu

Then it turns left and is supposed to continue following the black line towards the swing. We are using a reusable block for "tape follower". The robot works fine until it has to follow the tape for the second time. At that point It just does not do anything. If we substitute the second "tape follower" block with a simple tank drive block, the robot works fine. The turn blocks are gyro assisted blocks and work fine.
