each_with_index is outputting the array

I have a rails application that calls the helper method in the view by:

 <%= link_to_receipts @purchase_request %>

in the helper I have:

link_to_receipts purchaserequest
   purchaserequest.receipts.each_with_index do |receipt,i|
     #some code here commented out...
   end
end

but it outputs the array like so on the view:

[#>tagged_by: "joe somebody", purchase_request_id: 39, created_at: "2011-08-22 20:39:18",updated_at: "2011-08-22 20:39:18">]

If I comment out the each_with_index it will not show the array, but if it is there it will. Any ideas?

I found the problem. In the helper method I had the variable html first initialized in the block like so:

link_to_receipts purchaserequest
    purchaserequest.receipts.each_with_index do |receipt,i|
     html = ""
     #more code here
    end
 end

When it should have been declared outside of the block:

link_to_receipts purchaserequest
html = ""
    purchaserequest.receipts.each_with_index do |receipt,i|
     #code here
    end
 end
