删除行时，“字符串或二进制数据将被截断”

Im using Microsoft SQL Server Management Studio Express to connect to our SQL Server 2005 (think its 2005, its version 9.000 something something). I have a table with one column that saves a lot of text. I have set the column type to text. When i have a row with lots of text in this column i cannot delete it. I get the message "string or binary data would be truncated" when i try to delete it. If i try to edit the row i get the same message. What do i do?Im using Microsoft SQL Server Management Studio
