Hi, I have a field that I need to make sure is alpha characters only. I was wondering what I have to do to validate that the field only contains letters and spaces? I can easily make it so that it looks for letters only, but whenever a space is entered, it records it as an error.

 You need to add a validation rule to the field that says "fieldX" "does not match pattern" "Custom Pattern"... that pattern should be:

 (\p{L}|\s)*

This pattern specifies zero-or-more letter or space character.
