If you have Web Scraper 5.5 installed with SQL Server 2005, you can change your Datapage field length to -1 in the field properties->Tags (Manual) tab.
Then you need run the following SQL Server Query to update your database settings so that Web Scraper knows how to interpret fields with length of -1:
use ProvidusDB
INSERT INTO [ProvidusDB].[dbo].[settings]
([name]
,[val]
,[datatype]
,[parent])
VALUES
('IsSql2k5'
,'true'
,'bool'
,null)
