Validation After Data Entry

[Joseph31]

Ok its been along time since I have been on this forum.

I have three fields: InFile (Yes/No), Who (Pull Down Menu 4 Items) & Date Field (Date Format)

I can not figure out how to do a data validation on theses three fields...

I would love something like this:

When Infile="NO" & Who=Empty & Date=Empty then no error is given

When Infile="Yes & Who=Filled & Date=Filled then no error is given

When Infile="NO" & Who=Filled & Date=Empty then Error

When Infile="NO" & Who=Filled & Date=Filled then Error

I think i should use the case function but I do not how to do 3 fields

What about the if function?

Should I do this in the validation field or just a calculation field?

Help

Create a calculation as follows:

Case (Infile="NO" and isEmpty(Who)=1 ; Error)

You don't need to reference "Date", as there is an error if date is empty or filled.

Wow, that was quick thank you...

What if I wanted the Error to appear in a seperate field so i could format the way i would like....

Would i just have to put this case function in the field or is there someting else i would have to do?

Thank you for your quick response

I'm unsure whether you've given us all of the possible conditions that you want to watch for. For instance, what if InFile = "No" and Who = empty and Date = filled? Or what about when InFile = "Yes" and Who = empty and Date = empty?

First, define what is required. Don't worry for the moment about when the error will come up, just when it won't. For instance, I think that the following is true:

When InFile is "Yes", Who and Date must be filled in.

When InFile is "No", Who must be empty.

I think this covers all four of your rules. In addition, it says that the first case I mentioned above (InFile = "No", Who = empty, Date = filled) is OK, while the second one will produce an error.

OK, so for the validation to occur, the following calculation must be TRUE:

( ( InFile = "Yes" ) and ( not IsEmpty( Who ) ) and ( not IsEmpty( Date ) ) )

  or

( ( InFile = "No" ) and IsEmpty( Who ) )

Now, for each of your three fields, enter that calculation into the Validated by Calculation dialog box that you see when you go to the field options in Define Fields and click on the Validation tab and then the Specify button next to that checkbox. When any of the fields change (and the record is committed), the calculation will evaluate, and if it returns TRUE, then the user won't see anything. If it returns FALSE, the user will see a dialog box. You can also allow the user to override the validation when it fails, and/or show a custom message.
