ErrorMessageSchedule.Text (outside GallerySchedule) returns Blank, while the per-row label inside the gallery correctly shows "WARN: Planned DEV Start Date should be future day".
Reason
The outside label's formula likely references a gallery-template control (e.g. LabelScheduleGalStatus.Text) directly. Controls inside a gallery template only exist per row — there's no row context outside the gallery, so the reference resolves to Blank.
Fix
Capture the warning into a collection
Inside the gallery row (e.g. in the per-row label's OnChange, or in your existing batch update logic), push the warning text into a collection:
powerfxCollect(colScheduleWarnings, {Item: ThisItem.ID, WarnText: LabelScheduleGalStatus.Text})
(If you already maintain colScheduleGal, add a WarnText column there instead of a new collection.)
Update ErrorMessageSchedule.Text formula
Replace the current formula with:
powerfxFirst(Filter(colScheduleGal, StartsWith(WarnText,"WARN:") || StartsWith(WarnText,"ERR:"))).WarnText
Default value
Wrap with IfError/Coalesce to avoid blank-on-no-match:
powerfxCoalesce(
First(Filter(colScheduleGal, StartsWith(WarnText,"WARN:") || StartsWith(WarnText,"ERR:"))).WarnText,
""
)
