Date Stamp for Cell update - google-apps-script

Question

Using a Google App Script to show when a Stock Take cell has been entered or updated.
using the following simple script:
function onEdit(ss) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("StockTake"); // StockTake is the sheet where data is entered
var activeCell = sheet.getActiveCell();
var col = activeCell.getColumn(); // numeric value of column, ColA = 1
var row = activeCell.getRow(); // numeric value of row
if (col == 2 || col == 3 || col == 4 || col == 5 || col == 6 || col == 7) {
sheet.getRange(row, col+6).setValue(new Date()).setNumberFormat('DDD, MMM dd');
}
}
Problem is that sometimes the Column Header will also Date Stamp. I would like to know how to go about keeping the first row from getting a date stamp.
Thank you!

To avoid stamping the header row, you want to make sure that row > 1. So, add that to the if-statement.
While doing that, also simplify the condition for column: it's 2 <= col <= 7, which is expressed as
if (row > 1 && col >= 2 && col <= 7) {
sheet.getRange(row, col+6).setValue(new Date()).setNumberFormat('DDD, MMM dd');
}
