How do I get the onEdit script to run

Question

I've created a spreadsheet then added some values. I opened the script editor through the menu and added an onEdit function. I cannot, for the life of me, get that script to do anything when I edit a cell in the sheet.

It will run if I specifically press the "run" button in the editor, but that sort of defeats the purpose. What am I missing?

in case it matters here is my code

function onBugEdit() {
  Browser.msgBox("test");
  var sheet = SpreadsheetApp.getActiveSheet();
  var rng   = sheet.getActiveRange();
  var val   = rng.getValues();
  var col   = rng.getColumn();
  var row   = rng.getRow();
  var h_string = '=HYPERLINK("http://example.com?id='+val+'","'+val+'")';
  if(col == 4) { 
    col = "D";
    cell = sheet.getRange(col+row);
    cell.setFormula(h_string);
  }
};

The project trigger is set for the onEdit function but again nothing happens when I edit a cell.

Answer 1

Have you tried calling your function onEdit not onBugEdit ?
Also remember that "edit" is registered when you exit the cell after editing it.

your code could be simplified to:

function onEdit(e) {
  if(e.range.getColumn() == 4) { 
  makeHyperlink(e)
  }
};
function makeHyperlink(e) {

    e.range.setFormula('=HYPERLINK("http://example.com?id='+e.value+'","'+e.value+'")');
};
