Missing data

```
Hey there, I have a slightly modified version of your script, but I checked
a default copy to make sure it was an issue instead of my problem.
For some reason, certain values are not being saved.
I know part of it is the way excel is saving the information. I noticed a
few numbers aligned as if they were text, but I fixed those.

I'm attaching a sample file. Specificly, the part number fields are not
showing up...

Start by reproducing the issue with the attached dx.xls file and the default copy of the script. Trace how the reader handles the part number fields and compare those values with the spreadsheet. Done means the part number fields and other affected values are returned correctly from the sample file.
