title: Excluding Cells Without Numeral Values in a Range for an Increment Function
body: <p>So I have this function where I want to Add one increment to every Numeral Value in the B Column. I have this currently which works but it also tags a one onto the end of each Instance of Age In my Sheet. This is the current function:</p>
  <pre><code>function AgeUp(){
    var cell = SpreadsheetApp.getActiveSheet().getRange(&quot;B6:B70&quot;);
    var cellValues = cell.getValues().map(function(row) {return [row[0] + 1]}); // Modified
    cell.setValues(cellValues); // Modified
    
  }
  </code></pre>
  <p>And so basically I'd like to have it Add one to all in column B but only if they have a numerical value. How do I do this while also exclude those without numbers in them?</p>
