Originally posted by: ltollesonThe first parameter of the evalIf function must be a constant literal boolean value. It can be a literal TRUE|FALSE that comes from a boolean parameter or can be a constant value expression that produces a TRUE|FALSE. It cannot be a variable expression that produces either TRUE|FALSE.
In this case you should use the If Then Else statement.
value = if {{^Param1^}}.len() > 1 then <some value> else <alternate value>
