I was following the tutorial https://docs.flexsim.com/en/21.1/Tutorials/ProcessFlow/Tutorial4Instances/4-1BuildModel/ and did the model attached. I would appreciate tell me why my Sticker Machine is not resuming. By the way, some screens related to the custom code activity are not update and in the current tutorial (21.1), it shows the olds screens. Thanks, Tutorial 4.1 PF.fsm
