Combo Box entry for query problem

John,
I finally got it to work. I was using the "All Lines" option in the combo
box. I tried what you had and it didn't work. But, I changed it too the "Is
Null" option and now things are going my way.
Thanks for you help

eeep!

Try

SELECT FPYQueryByDate_STEP1.Date, FPYQueryByDate_STEP1.Line,
FPYQueryByDate_STEP1.SumOfNo_of_units_produced,
FPYQueryByDate_STEP1.SumOfNo_of_units_repaired,
FPYQueryByDate_STEP1.SumOfNo_of_defects,
(([SumOfNo_of_units_produced]-[SumOfNo_of_units_repaired])/[SumOfNo_of_units_produced])
AS FPY, ([SumOfNo_of_defects]/[SumOfNo_of_units_produced]) AS DPU
FROM FPYQueryByDate_STEP1
WHERE (((FPYQueryByDate_STEP1.Date) Between
[forms]![mainform]![startdatebox] And [forms]![mainform]![enddatebox])
AND
((FPYQueryByDate_STEP1.Line)=[Forms]![mainform]![line] OR
[Forms]![mainform]![line]="All Units"));

This assumes that the BOUND COLUMN of the combo box contains "1", "2",
"3" and "All Units" - if the visible column is different from the
bound column, open the combo's rowsource query and substitute the
value in the bound column for "All Units", or use IS NULL if that
field is in fact null in the query.
