I've browsed the tool mastery sessions on the Error Message tool, but was unable to find what I need.
I am building an app with multiple questions - some are drop-downs, some are free form text.
For the free form text tools, I have a field that must begin with the letter "i". I want an error message to appear when the user has omitted the i.
I also need to restrict one of the entry tools so the user receives an error message if they enter anything other than numeric values.
I've been unable to find the right expressions to use within the error message tool. For the first one, I tried Startswith([#1], !"i") - but the message is that I tried to apply a string operator to a numeric value. I'm sure there is a better way to do this. Looking forward to your assistance!
