Hi,
I tried fx int('30'') and and fx int(30), it came up with the following error n each occasion:-
invalidTemplate. Unable to process template language expressions for action 'Condition_3' at line '1' and column '23807': 'The template language function 'less' expects two parameter of matching types. The function was invoked with values of type 'String' and 'Integer' that do not match.'.
Thanks for your help so far.
