Author Syntax Question

Hi,

I want to evaluate 2 things, "Area" and "SubsQuestions"

I need to know if Area = "Six" or Area = "Seven" AND SubsQuestions =
"Yes"

Is it

....... If Area = "Six" or Area = "Seven" AND SubsQuestions = "Yes"
Then

or

....... If Area = "Six" AND SubsQuestions = "Yes" or Area = "Seven" AND
SubsQuestions = "Yes" Then

To confirm...... Six and No is to be ignored
...... Seven and No is to be ignored
...... Seven and Yes will be dealt with
...... Six and Yes will be dealt with

I'm getting just typing it!

Thanks

Jon

Simple grouping

If Area = "Six" or (Area = "Seven" AND SubsQuestions ="Yes") then

Thanks.

So I can have:

If Area = ("Six" AND SubsQuestions = "Yes") or (Area = "Seven" AND
SubsQuestions = "Yes") Then
'Do stuff
Else
'Do not
End If

Cool :)

No, that is not possible - the first parenthesis is in the wrong location:
it needs to be infront of Area:

If (Area = "Six" AND SubsQuestions = "Yes") or _
(Area = "Seven" AND SubsQuestions = "Yes") Then

It's also too verbose. This does exactly the same thing (the commutative
property applies to boolean operators as well as arithmetic operators):

If (Area = "Six" or Area = "Seven") AND SubsQuestions = "Yes" Then

Whoops that was a typo, however, your last solution is the neatest -
thanks Bob

Yes; though your first set of parentheses is wrong.
Also, for readability, take a look at this:

If (SubsQuestions = "Yes" And Area = "Six") _
Or (SubsQuestions = "Yes" And Area = "Seven") Then
'Do stuff
Else
'Do not
End If

I prefer for readability:

SQy = SubsQuestions = "Yes"
A6 = Area = "Six"
A7 = Area = "Seven"

If SQy AND (A6 OR A7) Then
'Do stuff
Else
'Do not
End If

or:

SQy = SubsQuestions = "Yes"
A6 = Area = "Six"
A7 = Area = "Seven"
A6orA7 = A6 OR A7

If SQy AND A6orA7 Then
'Do stuff
Else
'Do not
End If

To use a bit of both your suggestions
testQ = (SubsQuestions = "Yes")
test6 = (Area = "Six")
test7 = (Area = "Seven")

IF testQ then
IF test6 OR test7 THEN
'Do stuff
END IF
ELSE
'Do not
END IF

Sorry, that's not equivalent;you don't handle:
IF test6 OR test7 THEN's ELSE

yes it is,

first subquerys must be true or it fails, only if subquerys is true need we
test test6 or test7

Sorry, it's not.

If the second test fails you do not perform "Do not".

IF testQ then
IF test6 OR test7 THEN
'Do stuff
ELSE <= you don't allow for this
'Do not
END IF
ELSE
'Do not
END IF
