ComboBox Not Saving to SharePoint

Problem: ComboBox selections are not publishing to SharePoint list.
Fix:
1
Unlock the DataCard (if needed)
2
Set the Update property of the DataCard:
Field Type
Update Property Formula
Single Choice
cmb_Co­ntr­olN­ame.Se­lec­ted­Value
Multi Choice
cmb_Co­ntr­olN­ame.Se­lec­ted­Items
Text Field (Comma­-se­par­ated)
Concat­(cm­b_C­ont­rol­Nam­e.S­ele­cte­dItems, Value, ", ")
Notes: Ensure ComboBox items match SharePoint choice options exactly to avoid submission errors.
