Regarding Attribute Writing

I am working with an Excel data.After applying cluster algorithms on it,I couldn't write the text data in to Access database.But it is allowing to write the "cluster" column.Whenever I am trying to write the text data an error displaying like "Database error occurred: [Microsoft][ODBC Microsoft Access Driver] Syntax error in field definition" (I think the size of the data is too long).How can I solve this problem.Here I am attaching my process.

    use a real database and not Access if you want to store large texts. You might install the RapidMiner + Ingres bundle on a windows system for most convenient access on a database.
