I’m using Matsimitsu’s Barcode Generator:

> **[GitHub - matsimitsu/barcode-generator: Rails plugin to generate/display...](https://github.com/matsimitsu/barcode-generator)**
>
> Rails plugin to generate/display barcode in your views - GitHub - matsimitsu/barcode-generator: Rails plugin to generate/display barcode in your views

and have installed: gbarcode (0.98.16), rmagick (2.12.2) and have  
installed the files to: Vendor/Plugins/ directory and successfully ran  
the rake barcode\_setup command to create the public/images/barcodes  
dir.

I Tried using the sample code: \<%= barcode ‘FJJ4JD’%\> in one of my  
html.erb files, with the returned message:

* * *

NoMethodError in Inventories#show  
undefined method `barcode’ for #ActionView::Base:0x105bb8838

Did I install this incorrectly? Am I using this incorrectly?

Any help would be GREATLY Appreciated

Thank you in advance Google Ruby on Rails Talk Folks!
