Customer Input field help

[itye2012]

I am designing an art canvas website. One of the options when buying an art canvas is to specify a name to place on the canvas. I have created a custom field plugin and selected the plugin VM_Custom, customer text input.

I gave it the custom field title "Customised", this works ok and at the cart the customer enters the name they want on the canvas however when the item is added to the cart and the cart is viewed the headings appear twice, eg as the heading of the custom field was "customised", customised appears twice in the cart summary area!
Can anyone help or advise another way of allowing customers to enter a value ?
Thanks
