I don't understand why this siple concatenation from form ends up NaN

You're referring to the wrong component, should be havestTimeEntryIdInput :wink:

Hi @AM-BE
Thank you for the response.
But I don't et what you mean.
harvestTimeEntryIdInput instead of harvestTimeEntryIdInput.value?

My bad @KMimpact I was looking at the wrong part of the transformer in your first screenshot.

You've put a * instead of a + operator in your transformer. That should fix it!

@AM-BE
OMG this never stops happening... :sob: :sob: :sob:
Thanks for pointing out really appreciate it and now it worked
