AS you talk of Text field, is this MS SQL Server Text? Or what text field do you mean? VFP has several types of fields, which store their data into the fpt file, one of them is memo and has a variant binar5y memo, bu no matter what memo type, it can store string data.
Data Type mismatch really points to a wrong field type as the source. Debugging (eg via SET STEP ON or a breakpoint before the INSERT, UPDATE, APPEND, REPLACE or whatever you use to insert into the memo field should enable you to look at the real source data type.
