You have a problem because you are trying to compare things from two different messages. Alas this doesn't work. You need to join them so they become one message. I will have a look at what is going on and see if I can get things working quickly for you. Oh and in the change node, it may have be…

[image] seyeon: I also tried to join(join node) the two data, but It doesn't work, too. The Join node is a good way to go, but it is necessary to configure it correctly. Have a look at this link to an example in the cookbook, and show us what the problem is if it doesn't work. https://cookb…
