I’m trying to avoid having a certain user field be shared by multiple users. I set this condition, however, the condition only catches it if the value has the same exact capitalization.

Since “Do a search for” requires a value, and it seems it’s case sensitive, it’s unable to find all potential values with the same characters. Let’s say I have a Data type with a Company Name field and Microsoft already exists. When someone else tries to add a new record with the same Company Name I want to disallow submission. So I want to ensure that all variations of case that a user types into an input field (“…
