Please do not double post - it splits volunteers attention and efforts and scatters information in a way that is less useful for those who look for similar answers later. Closing this thread, leaving other post open.

Re-opened as other post hijacked a thread with different subject matter not related.

You sure - it’s turning in to an edit-fest here.

I’ve put your code back so you can answer the question that is really rather pertinent to your question - where did that code from.

Going forward, please format text/code/JSON/logs with the </> tool
