Error Executing Workflow On User Input Script

My scripts were working a few months ago. As far as I know, nothing has changed. I have not added or modified any of the fields nor the scripts that access the fields.

This week I needed to add new records and update some existing records. I received the following error:

The field CONSULTATION STATUS is changed from either "NEW" or "IN PROCESS" to "COMPLETE" when the consultation is done and I click UPDATE. At that point I have code to calculate some totals and percentages. Here is the script I have been using. I would really appreciate if someone could point me in the right direction.

As you can see, the error states ERROR on evaluating criteria line: (4) I'm not sure exactly what line 4 is referring to.

After I close the error and attempt to SUBMIT the form again I get the error:

"Invalid entries found. Please correct and submit again."

Due to this, I can no longer get the totals and percentages to calculate. This is vital to the report where I display these numbers.

Thanks!
