all the commented objects also need fixing if anyone wants to throw

The paren in this line doesn’t seem closed, and you may forget  
qoutes?

What options did you call the script with? Whatever, your use of  
OptionParser is wrong. You are asking for date options with no  
arguments where you should be asking for arguments:

opts.on("-s", “–startdate”, “Determines what start date to use.”) do

Should be:

opts.on("-s", “–startdate DATE”, “Determines what start date to  
use.”) do

And the same for the end date and output options. Check the  
OptionParser docs. There are other bugs in there as well: “ARGV =  
svg” should surely be “d = ‘svg’” for instance.

Maybe, one of them (or both) is nil?

well after fixing those few flaws i get a huge nomethoderror from the  
method .column such as verizondat.column …understandable because it  
is actually supposed to use table.column but in fact table is tied to

table = Ruport::Data::Table.parse(csv)

which parses the data, not the grep’d array…so i guess my question now  
would be how do i perform the same function except on the grep’d data?

-Thanks
