Option Buttons to Pass Criteria to Query

Hello,

I have a form that has some unbound controls that pass criteria to a
query that displays in the lower half of the form. One of the fields
I have criteria for is a yes/no field called invalidEmail. The values
are yes if the email is invalid; no if the email is valid. In the
query, I want the user to be able to display (1) only records with
invalid emails or (2) only records with valid emails or (3) all
records. I tried a form checkbox where in the query, the criterion is
forms.fm__.checkbox, but that will only give me displays 1 and 2.

So, I tried 3 option buttons, but because they are numeric, I can't
set a value at * to get select all. So I tried the following
statement:
IIf([forms].[fmQryByClinic].[emailOptions]=1,True,IIf([forms].
[fmQryByClinic].[emailOptions]=2,False,"*"))
Access doesn't like this if [emailOptions]=3, which is my intended
"show all" button, or if no options are selected. The error message
is "The expression is typed incorrectly or too complex to be
evaluated...."

It doesn't seem right, but I also tried:
IIf([forms].[fmQryByClinic].[emailOptions]=1,True,IIf([forms].
[fmQryByClinic].[emailOptions]=2,False,IIf([forms].[fmQryByClinic].
[emailOptions]=3,"*","*"))
Access doesn't like that either, same error.

Does anyone know what I'm missing here?

Thanks,
Dara
 
If you enter the following into a criteria cell under your field you should
get the desired results. It will get restructured in the query design view
when you save the query.

IIF([forms]![fmQryByClinic]![emailOptions]=1,True,IIF([forms]![fmQryByClinic]![emailOptions]=2,False,Null))
OR [forms]![fmQryByClinic]![emailOptions]=3

Try this --
Like
IIf([forms].[fmQryByClinic].[emailOptions]=1,True,IIf([forms].[fmQryByClinic].[emailOptions]=2,False,"*"))
 
Try this --
    Like
IIf([forms].[fmQryByClinic].[emailOptions]=1,True,IIf([forms].[fmQryByClini­c].[emailOptions]=2,False,"*"))

Build a little, test a little.

Thanks for trying, but that's the same as the first code I listed in
my post, it doesn't work.

Your suggestion worked perfectly, thanks a ton! Now I have to stare
at it and figure out why... :)

Explanation:
The first test is applied against your field.
IIF([forms]![fmQryByClinic]![emailOptions]=1,True,IIF([forms]![fmQryByClini­c]![emailOptions]=2,False,Null))

In a Where clause
WHERE [YourField] =
IIF([forms]![fmQryByClinic]![emailOptions]=1,True,IIF([forms]![fmQryByClini­c]![emailOptions]=2,False,Null))

After the IIF is evaluated that is going to be
WHERE [YourField]= True (or False or Null)

The second test is actually is going to return TRUE or FALSE and does not
involve your field at all.

WHERE [forms]![fmQryByClinic]![emailOptions]=3

Records are returned when the WHERE clause evaluates to TRUE

SO
WHERE ([YourField] =
IIF([forms]![fmQryByClinic]![emailOptions]=1,True,IIF([forms]![fmQryByClini­c]![emailOptions]=2,False,Null))
OR [forms]![fmQryByClinic]![emailOptions] = 3)
evaluates to return the desired records.
