Contains[Field] that has exactly 4 characters

[wonka1234]

Hi,

I have this ina  multi row formula - 

IF Contains([Field1], "A") THEN [Field1] ELSE [Row-1:Field1] ENDIF

I want to add an OR contains for strings with 4 digits/chracters.

Thanks.

Try this. 

IF Contains([Field1], "A") or REGEX_Match([Field1], '.{4}') THEN [Field1] ELSE [Row-1:Field1] ENDIF
