first of all, I've been able to append text data to a Numeric field (Field Size was Double) without having to do any conversion, so I don't understand the problem you are having. Terry's example was to use the CDbl or Convert to Double function which would have converted the text string type to a numeric double type. If you are concerned about Access dropping the trailing zero off of the Decimal places, simply change the Format for the Numeric Field To Fixed.
