Script not running at document open

I have the following script in my "Documents JavaScript." It is my understanding putting the script in "Documents JavaScript." should cause the script to execute each time the document is opened.

The intent is to look at three fields in a specific row... if all are $0.00 and a date has been put in the date field for that row, then remove the date. If any one of the three checked fields has a value >$0.00 then leave the date. The field is defaulted to currency, thus the Dollar sign. I have tried both with and w/o the "$." This is repeated 8 times as there are a possible 8 rows all with the fields as noted in the script.This is not working on testing. What am I missing or is this not going to work as is?
