What was the issue you found by yourself.... let me check if our understanding matches with you.... ;P

function OpenInNewTab() { // window.open('http://w3schools.com', '_blank'); window.open('http://localhost:2319/test.aspx', '_blank'); }; test

I just learned this myself. When you define your function Greet(), you need to define it with something inside the parenthesis so the function expects to get data to then be used in the function. So you would define Greet() instead as Greet(var). In this case var is any variable name you choose. Greet can then use var in the function for whatever purposes it needs. When you call Greet, you would put a string or other variable name inside the parenthesis: Greet("Sue") or Greet(namex). The function will then treat that as var. :cool:Hope that was clear enough to help!
