Expression Builder Blues

[justphilip2003]

I do not seem to be able to code selective code, for example

=[FName]& " " & [LName] works beautifully but

=[Iff sex=”M”,”Mr. & “, “Ms. & “ [FName] & " " & [LName]] gives me an invalid expression syntax error. I've tried all sorts of variations like

=[Iff sex =”M”,”Mr “, “Ms“] & ". " & [FName] & " " & [LName]] with similar errors.



I have similar bad results with Choose and Switch functions. Is there a trick involve that I am not aware of? TIA Phil

It would help if you had the right function name and parens, etc.

=[Iff sex=”M”,”Mr. & “, “Ms. & “ [FName] & " " & [LName]]

SHOULD BE

=IIf([sex]=”M”,”Mr. “, “Ms. “) & [FName] & " " & [LName]

try,
iif([sex]="M", "Mr." & [FName], "Ms." & [FName])

EDIT: just noticed that Bob's post beat mine.
Bob's answer is more correct than mine.
I was giving an example of the iif() function, his gives a complete answer.

Gentlemen I used Bob's code and I get a little window asking for the Parameter value of "M". I am stumped! Phil

Could there be an Property field that needs addressing besides the control source? TIA Phil

Are you sure that the control or field name is named sex? Do you actually have that field in the form's control source and is it bound to a control on the form?

[justphilip2003]

I'm afraid it is. This db is about code and functionally not pretty or meaningful data; I threw in fields that were easy (I thought) to test. The Form ButtonMania has every possible button I could think of and data manipulation, in this case an unbound field using bound fields to populate the unbounded text box. Also, I corrected the code. Small print is difficult for me to see. =Iff([Sex]="M", "Mr. ", "Ms. ") & [FName] & " " & [LName]. Still when I try to save this code, I get a syntax error. TIA Phil

As was pointed out earlier, it's IIf not Iff.
