Including two choices in the entity in bot composer

[Sushmitasen32]

Hi,
I'm creating a weather bot where bot questions the user to enter the postal code. I've specified the condition for the length of the postal code to be either 5 digit or 6 digit and my bot is running successfully. But now I want the bot to fetch the weather details directly if user says, "How's the weather in 400614". For this , I'm using LUIS recognizer- As per the LUIS documentation ,this is the syntax for providing the entity-$ postalcode:/[0-9]{5} but I want to specify or condition to include 6 digit as well and not just 5 digit.
Can somebody guide me to specify the or condition i.e, if user enters the 5 digit or 6 digit zip code,bot should use this entity.
I've used this condition as shown in the image but this doesn't give me the output.
