Formula for converting a date to quarter and leaving blank cell for no date values

Hello,

I am a new member to the forum and have been having trouble with a formula. I am using ="Q"&INT((MONTH(F3)/4)+1)&"-"&RIGHT(YEAR(F3),2) to convert a date in F3 to a quarter and year in J3. Is there a way to have J3 show an empty cell until the data is F3 is entered so it doesn't show Q1-00?

Attachment included.

Thank you,

JC
