all choices from a combo box

[deekras]

i would like to be able to have the choice to select only one 'category' or all the 'categories'.

 

[ingvar68]

i do so:
if user nothing select in list that he selected all-
...
if isnull(me![LIST_NAME]) then
'all
else
'something
end if
...

or you may use special function to fill list with first value-all. see help.
glad to answer
