Passing String Text From MS Access to SQL Server - 128 Character Limit

My Question is:  How can I pass Text Strings form Access to SQL server when the string is greater that 128 characters in length?

I have Large string text stored in a MEMO table in MS ACCESS (being used to store large comments (up to but not more than 2000 characters)).  I declare an Access variable    "Dim myString as String" and set myString = the text from my MEMO field of my Access table.

Using an ODBC connection, I pass the myString variable to a SQL server table via a stored procedure. That procedure receiving the text as a parameter is:

@General_Comments [nvarchar] (Max),

I then Append or Save the value of the parameter of the SQL server table in with a field type of "nvarchar(MAX)".

My procedure works perfectly up to 128 Characters in length.  When I go to 129 Characters, the procedure fails. 

Help is greatly appreciated!  Thanks in advance.
