Do a qry that lists all the variations
Of your data.
e.g. say if they select 1, in box two 1
Could come in w,e,h. if they select 2,
box two could come in w,p,v.if they select 1,w,
box three could come in p,l,o BUT if they select
1,e, box three can come in a,b,c.
you need a qry of this
Create your 4 combo boxes using the wizard
base them on your qry.
call the first pick1
2nd pick2
3rd pick3
4th pick4
go into properties of combo1 click on the 3 dots
... next to row source.and do the grouped by thing.combo1
should be (your number selection)
then go into the same bit in the second combo and in
the criteria [Forms]![nameofform].etc.
e.g.i had pickDrug1, pickForm1, pickStrength1, pickFrequency1.
i went into pickDrug1 properties-row source-then did group by
(in this combos row source qry there was only one column

rug)
i went into pickForm1 properties-row source-did group by and went
to the criteria (in the first column) underneath Drug.
(In this combos row source qry there was 2 columns

rug+Form)
