If Blank using Match and Index

How do I add a statment to this formula to say:
If I5 is blank, do nothing...otherwise do what the code says below?
I tried adding it in different ways but it doesn't work.

=IF(ISNA(MATCH(I5,code,0)),"-",INDEX(description,MATCH(I5,code,0)))

=IF(I5="","",IF(ISNA(MATCH(I5,code,0)),"-",INDEX(description,MATCH(I5,code,0))))

AWESOME! Thank you!
