Recipe Function - pass variables/information IN

Hi guys,

Can anyone advise how to pass variables/information from a Parent Recipe INTO a Recipe Function?  I have scoured the internet this morning and neither the Workato documentation, nor any other source, has any info I can find on it.  Am I misunderstanding something?  

I have entered the desired parameters in the Parameter Schema in the Recipe Function, but not sure how to pass variables/information from the Parent Recipe into these parameters for use within the Recipe Function

Please help!

EDIT:  Sorry, was advised all I had to do was refresh the Parent Recipe to see the variables appear in the Recipe Function step!
