Populating Excel Columns and rows from VB.net

Hello,
I am trying to populate an the following columns in an excel spreadsheet from vb.net
Budget Year,
Policy Case,
Budget Case,
Version
I am deriving these value via a split function applied to the dataversionid column.  When I run the program, I keep getting the following error.  I'm not sure what is causing it.  Thanks
