i am not sure what is wrong here  
tablearr is of type FASTERCSV::TABLE  
eachrow is of type FASTERCSV::ROW  
as per the fastercsv doc, the table.values\_at returns a array.  
the array has method .include?

def checkduplicates(eachrow,tablearr,indx,criteria)  
eachrow.each{|name,valu|  
rowdata=tablearr.values\_at(indx+criteria)  
if(rowdata.include?valu)\<\<\<\<\<\<\<\<\<\<\<\<\< ERROR HERE.  
puts “match”  
end

}

c:/ruby/lib/ruby/gems/1.8/gems/fastercsv-1.2.0/lib/faster\_csv.rb:  
345:in `==': undefined method`row’ for “03”:String (NoMethodError)  
from scan.rb:7:in `include?’

I’m happy to help debug this, but it would be much easier if I had  
some code I could run. Could you try reducing the error to a simple  
little script, using included dummy data, that shows the problem?  
When I see that, I’m sure I can provide some suggestions.
