    'False' error message 'The value that you entered isn't valid for this field'

    Since the last post, I have completed the core of the database except for one remaining look-up table. The monthly data exports are workig as required (making use of the datestamp fields). Append queries are working thus speeding up data population. However, I still have the errror message. This...

    'False' error message 'The value that you entered isn't valid for this field'

    Thank you for the response, I too always prefer to solve a problem rather than smear over it, I am just having to balance the triple conflict of having to produce a result at the same time as developing the database and simutaneously learning Access (having been used to Borlands Paradox)!! > I...

    Multiple Column Lookup Display- table & form (2)

    Many thanks, it did indeed help. Some points for less experienced Access database builders; Microsoft did not like me typing in "SELECT" so the Row Source only worked after using the query builder. I still only saw 1 field until I noticed that only one column width was defined !! I defined the 5...

    I have worked for many years in documentation & data management and have specified many databases, small and large, but am not a programmer. All my personal databases still run in Borland's Paradox (that uses a C++ based ObjectPal language). I have used Access on and off for the past 13 years...
