How can we determine user story valuable to end customer?

Question

In Agile software development methodology, it says that a good user story must be "INVEST".

 

I=Independen

N=Negotiable

V=Valuable

E=Estimable

T=Testable

 

What exactly mean of "Valuable" of "INVEST"?

 

Would a user story valuable if it is not adding any direct value to the customer or end user?

For example: In a user story I am adding an input field in UI but it would be used while saving record that would be completed in another user story.
