How would I know without the incoming data you used.

p.s. Did you use the new edited change nodes? I posted an edit in post above.

[edit] Moved the chnage node expressions into the function node code.

Did not see the change and then overlooked the change to the change node of the topic. -.-

It seems to be working now. I will do an extensive test and report back 🙂

You make it look so simple 😃
