Problem with FTS

I am trying to setup Full Text Search Service on my SQL 2000 Server Database
The problem I am having is that the "NEXT" button is not setting to enable when I select all IMAGE column to be populate
Why is it behaving like this ? am I missing something? I attach the Table structure & FTS Image link
Please help me

This is also my Table structure

The text below is from the BOL(books online) about the extra column requirement to use Image column in Full Text index.
Run a search for Full Text image column in the BOL (bboks online) for more info. Hope this helps.
(Thus, when you set up full-text indexing on an image column in a table, you must create a separate column to hold information about the document. This type column can be of any character-based data type and contains the document file extension, such as doc for a Microsoft Word document. If the type column is NULL, the full-text service will assume the document is a text file.

In the Full-Text Indexing Wizard, if you select an image column for indexing, you must also specify a Binding column to hold the document type.

The sp_fulltext_column stored procedure also accepts an argument for the column to contain the document types.

The sp_help_fulltext_columns stored procedure also returns column name and column id of the document type column. )
