I am trying to ask the data entry users to enter an email with the below format
My question is what is the type should be and also where I should put the regex function. Is it under constraint.
Hi. The help topic Formulas—Survey123 for ArcGIS | Documentation , in the Regular Expressions section describes how to use regular expressions in Survey123. The expression you have works well as a constraint when tested in Survey123 Connect. Just keep in mind that constraints are only checked when you attempt to submit data, or if within a repeat, when you attempt to move to the next record in the repeat.
