Element Hours Pass

Summary

How can you pass hours from one element to another?

Content

I have an existing Standard Earnings - Regular element "Source" this element has existed since go live in Jan 16'.  I have created another element that is Supplement Earnings - Bonus "Target"  

Priority for Source is 2500.  Hours x Rate. Periodicity is Hourly
Priority for Target is 3500. Hours x Rate. Periodicity is Hourly. Periodicity Conversion Rule is Standard Rate Annualize.

I'm am trying to pass the Source Input Value of Hours to the Target Input Value.

With what I did and I perform a Quick Pay, the Target element errors stating Periodicity has no default value, yet it has it in the Input Value of Periodicity, as well as, in the Element Eligibility Input Value.
