Clear the contents of each row in a column on one sheet, depending on the change in a column on the same row on another sheet

I'm struggling with this code, which works perfectly inside the same sheet, to get it work between two sheets. For an example if I change a content in cell E5 or in multiple cells in E column on "Sheet1", this clears a content in Cell A5 or in multiple cells in A column, depending on the row they are in.

function onEdit(e){
  var range = e.range;
  var row = range.getRow();
  // Check if column E and sheet "Sheet1"
  if(range.getColumn() == 5 && range.getSheet().getName() == "Sheet1") 
  {
    if(range.getHeight()>1)
    {
      // Multiple cells selection case
      var nbRow = range.getNumRows();
      var i;
      for(i =0; i < nbRow; i++)
      {
        var temp = row + i;
        e.source.getRange("A"+temp).clear();
      }
    }
    else
    {
      // One cell selection case
      e.source.getRange("A"+row).clear();
    }
  } 
}

Could any of you guys please help me with the code to get it work between two sheets, because it's already driving me crazy :/

Any help would be greatly appreciated!
