it is not a common practice to store calculated data to a table.
you can always derive the accurate result using a query, in case any value if any the field change


try this query

SELECT pontage.name, pontage.h1, pontage.h2, pontage.h3, pontage.h4, pontage.h5, IIf(IsNumeric([h1]),CInt([h1]),0)+IIf(IsNumeric([h2]),CInt([h2]),0) +IIf(IsNumeric([h3]),CInt([h3]),0) +IIf(IsNumeric([h4]),CInt([h4]),0) +IIf(IsNumeric([h5]),CInt([h5]),0) AS WH
FROM pontage;

I have one problem with this code. The query put in the "wh" a round value. For eample if i add H1 to H5 and the rezult is 5.8 then in "wh" i will have 6. How can I make the "wh" to show me the exact number with 2 decimals.

Thank you!

why didn't you specify in the first place that you have decimal values.


SELECT pontage.name, pontage.h1, pontage.h2, pontage.h3, pontage.h4, pontage.h5, FormatNumber(IIf(IsNumeric([h1]),cdbl([h1]),0)+IIf(IsNumeric([h2]),cdbl([h2]),0)+IIf(IsNumeric([h3]),cdbl([h3]),0)+IIf(IsNumeric([h4]),cdbl([h4]),0)+IIf(IsNumeric([h5]),cdbl([h5]),0),2) AS WH
FROM pontage;
