Can and attribute be prepopulated with a variable?

[tj1]

I have a product with an atribute with text entry and I was wondering if the text field can be prepopulated with some variable.

For example have the url link like
index.php?main_page=product_info&products_id=101&attribute_text=sometext

Then somehow use $_GET['attribute_text'] to obtain the text to prepopulate the text field.

Is this possible?



Thanks.
