MapPoint pushpins not showing on map

For some reason, my pushpins are not showing in my VB 2008 application.  When I use just the 3 columns as shown in this URL (http://www.mapforums.com/sitemap/t-11197.html) and use a simple dummy file with just "lat", "long", and "name", it works fine.  As you can see from the code, I have expanded this to accomodate more data, but now nothing shows on the map.  TIA.

Also, the bit at the end where it's supposed to center on a pin isn't working. I know for sure there is an entry by that name in the CSV.

The .csv file and the .rpt file are being created perfectly, but does it matter in which order the fields are organized in the csv?  Looking at the code, I didn't think it did.
