How to print to console when running a formula in google sheets (Logger.log used)

When attempting to print to the console using Logger.log when running a formula in google sheets nothing is logged. How can I fix this? I am trying to do this in this part of my code:

        **Logger.log(data[row][col]);** 

Code:

    /**
This is only a test
**/
function getLonnie(data) {
  Logger.log("hello");
  var myArray = [];
  var numTimesLonnie = 0;
  for(var row = 0; row<data.length; row++){
    for(var col = 0; col<data[0].length; col++){
      if((data[row][col]) === "Lonnie"|| (data[row][col]) === "Lonnie G"){
      numTimesLonnie++;
        myArray.push(data[row][col])
        **Logger.log(data[row][col]);** ---> I am trying to log while in a formula here

      }
    }

  }

  return numTimesLonnie;
}
