New Bug Encountered: Add New value only in uppercase for NUMLIST type

[Sebastian_Munoz]

Hi, everyone.
I am using a column [category] and is ENUM type.

And Allow other values, is some way to secure that if the user add a new value is in uppercase letter.
With other columns i use this valid_if expression IF( FIND(UPPER([_THIS]), [_THIS])=0, FALSE , TRUE) and it works.
