JavaScript Trouble declaring and referencing global array in JS

Define a global variables from the window object:

window.iListCount = 0;
window.arrListItems = [];

Are you only using iListCount as an index for arrListItems if so replace:

iListCount++;
arrListItems[iListCount] = sText;

with this:

arrListItems.push(sText);

And replace iListCount references with arrListItems.length.

I used the above suggestions in the following fiddle as well as some other good practice measures:
