>I Just discovered that it's not only this field but every Numeric if stretched to its limits. A N(5.2) will trigger the error when 111.11 is in the field. I still don't know why this is, so any help is stil appreciated.

I don't know if its a "bug" or a "feature" but the numeric field's width must be at least one digit more than the width of the largest numeric value to be stored.

HTH,
