Populate same Cell with 2 possible out comes with If(isblank)

Hi,
I am trying to populate a cell (R3) with 2 possible out comes, although I can't work out how to do it. Both formulas are below and are required in cell (R3). Basically if (T3) is populated with a date (R3) returns a completed statement, but I also require (R3) to return a blank cell if (S3) is not populated with a date.

=IF(ISBLANK($T3),$S3+365,"Completed")
=IF(ISBLANK($S3),"",$S3+365)

Any help would be appreciated.

Kevin.
