I have a field on a form where users must be copying and pasting the value from other sites as often it shows up in the database with 1 to 5 spaces before it. What’s the easiest way to prevent it from saving if there’s a space at the start?

You’re in luck if you want to remove that white space and only save the value https://bubble.io/reference#Data.Messages.text.trimmed
