How to: Output text field as link to external sites?

Hi,
i imported a huge list of companies for internal evaluation in a node type, and created a table view. Everything works fine, besides the formatting of the web-url field of those companies.

I tried everything offered within the views configuration of the field, but the exteranl links always get rendered as internal links:
For example, I checked "Output this as a link" and entered in "Link Path" the offered token [field_homepage_value]

The result is
http://www.mywebsite/www.company_A

instead of
http://www.company_A

I have no clue how i can get rid of my own domain path in the link.
Any suggestions ?

Cheers
Bernd
