Dear All,

I have an edit form with three toggle data cards and a save button which submits form.

I need to validate it and only allow one toggle to be true, how is best to do this, maybe on the save button?

Do you have some code for this and to output a message to a label?

Kind Regards

Daniel

Hi @DLCaterhamSch

You can achieve that by adding the toggles to a filter through a table:
If( CountRows(Filter([Toggle1.Value, Toggle1_1.Value, Toggle1_2.Value], Value = true)) >= 1, "Only one toggle can be true", "Please select one of the three toggles" )
If you have any questions or feedback, please let me know. Have a great day! 😊

You can add the code to the OnSelect property of the save button.
If( CountRows(Filter([Toggle1.Value, Toggle1_1.Value, Toggle1_2.Value], Value = true)) > 1, Notify("Only one toggle can be true", NotificationType.Error), SubmitForm(FormName) )

I also need it so that if no options are selected it errors? How would I do this?
