Just trying to display a date and time using FORMAT_DATETIME_LOCAL formula.
Its part of a repeating item so my formula is as below
the Date Month and Year appear in the composer pro screen as if the formula is correct.
But nothing displays on the app preview?
Might be that there is no data, or
created_at is not a valid datetime. I would try the repeat without the formula first with just
repeated.current.created_at to see what’s going on in the field.
Yes I tried to display just the time stamp as suggested. That’s works and displays the time stamp in the app preview and composer Pro.
Using the formula as above does seem to work in the composer Pro screen as I can display the data as defined by the formula out put “DD.MM” for example or “DD.MM.YY”
So it seems to be able to read the time stamp ( from Xano).
But it does not display anything in the app preview.
If ‘repeated.current.created_at’ is a Timestamp in Milliseconds then you need to convert that to ISO 8601 format first using the DATETIME function, ex: DATETIME(repeated.current.created_at)
Solution as below found. Thank you @JOHN_WORSHAM and @Mari would not of cracked that myself.
