Default Field value of check box based on other Fields- Custom Object

Content

Hi All,

I am new to Application composer & need help for below scenario:

1) We have created custom object to store data from 3rd party system via REST API.

2) Object is created with 6-7 custom fields.

3) One of field is Active(Checkbox) this needs to auto populated based on fields like Type & flag( both are part of this Custom object)

 

is there any way I can write Expression to default Active field based on Type & Flag?

Example if Type is 'OJ' and Flag is N than make Active = false else true.

Thank you in Advance.
