Hiding Rows based on information

Good morning,

I'm currently creating a report that displays within an app which shows the amount of days left till a date is approaching.  I have some customers based on import that have dates in the past therefore the formula I've created to calculate to give me the amount of days displays blank for some of them.

I was wondering if there is a formula or something that I could do that would hide the customers who do not have any information displayed within the field that does the calculations. 

Thank you all for your help as always!
