To change the values in the setupLinks function below.
You will notice there are two arrays for each of Titles and
Links. Currently there are 3 items in each array, but you can easily
expand on that by adding to the array. For example, to add a 4th record,
you would simply include the following 2 lines at the end of setupLinks
function:

arrLinks[3] = "someURL.htm";
arrTitles[3] = "Some title";
