Liahona,
Make sure that you have followed the instructions as per the modification. When I was installing it, I used the files provided in the attachment, without realizing that I actually need to copy and paste content from existing files and then change some of it.
The modification that I posted you can leave it out for the time being so that you don't get confused. Later on you can apply the modification along with Josh's Birthday 1.4.
If you wish PM me and I can email you my files so that you can compare them and see where you went wrong.
Warm regards
Nikos
