Error in Condition

[IPeter]

Hi Team, 

I am getting below error when using the Condition. Please help

Unable to process template language expressions for action 'Condition_2' at line '1' and column '3130': 'The template language function 'less' expects two parameter of matching types. The function was invoked with values of type 'Null' and 'String' that do not match.'.
