title: Return blank cell only if referred cell is blank, but return aging if date is entered
body: <p>I'm attempting an aging formula. I have one column with dates I've submitted info, but some rows in the column haven't been submitted. In another column I want to have an aging formula. If the "submitted date" cell is blank, I want the aging cell to be blank. If there is a date entered, I want it to show how many days it's been since it was submitted.</p>
  
  <p>I'm pretty new to excel formulas. I know how to create the aging, and I know how to make one cell blank if another is blank. But I do not know how to combine both formulas into one cell.</p>
