Question
QUESTION: Hello,

I am working on a query that has mutliple dates.

This is the table structure

RequiredStart
RequiredEnd
Signature1
Signature2
...

I am trying to build an IIF statment for a column in a query to say either Violation or In Compliance.

Signature 1 and Signature 2 need to fall within the RequiredStart and RequiredEnd. If that is the case the field should dispaly In Compliance if they are not both within the dates it should say Violation.

Also if one of the dates are missing it would say violation.

This is what I have so far
Violation: IIf([Signature1] Between [RequiredStart] And [RequiredEnd],"In Compliance","Violation")

I could not find a good example of a nested date expression.

Please help if you can

Thanks
Ryan


ANSWER: This isn't a nested anything. Try it this way:

IIF([Signature1] > [RequiredStart] AND [Signature1] < [RequiredEnd],"In Compliance","Violation")

QUESTION: Yes that works however it does not incorporate signature 2. Can this be done in one statement? It should be a violation if signature 2 is also missing or otuside of the required start and end.

Answer
Try
IIF(([Signature1] > [RequiredStart] AND [Signature1] < [RequiredEnd]) AND (Signature2] > [RequiredStart] AND [Signature2] < [RequiredEnd]),"In Compliance","Violation")
