How do I write this IF THEN ELSE logic

How do I write this statement?

If :
VarName1 is true
VarName2 is True
Then:
Call Sub1
Call Sub2
If:
VarName3 = "NotString1"
Else:
Call Sub4

If VarName1 = True Then If VarName2 = 1 Then Call Sub1: Call Sub2: If
Varname3 = "String1" Then Call Sub3 Else Call Sub4

Evrything I try is good up to the ELSE option.

Thank you,

Which 'If' is the 'Else' to?
I guess it is the 'End If' that is the problem.

I have no idea what the logic is intended to be but assuming VN1 and VN2
must be True then something like

If VN1 And VN2 Then
Sub1
Sub2
End If

If VN3 = "S1" Then
Sub3
Else
Sub4
End If

That, of course, assumes the two cases are independent--if the test for
VN3 is only intended to be true for the case when VN1 and -2 are True,
then that If...Else...EndIf needs to be moved inside the previous.

You need a well-formed truth table to decipher what is supposed to
happen when, then implement that rather than just throwing stuff around
willy-nilly and see what happens...

If VarName1 then
if VarName2 then
Call Sub1
Call Sub2
Endif
ElseIf VarName3 = "String1" then
Call Sub3
Else
Call Sub4
Endif

Or thereabout

there is a ':' that is a lot like a label, or am I thinking wrong...
so u created labels if: then: and else:, but it (the compiler) should
have complaind about that 2Nd if...
So the end if is not the initial prblem, but it will be when the :
leaves as G S suggested

you'd save everybody a lot of grief trying to work out what you want, if you
just INDENTed your algorithm.

ie is your statement

IF
vn1 is true and (???) vn2 is true then
call sub1
call sub2
if vn3 = "notstring1" (THEN) ???

endif (???)
else
call sub4
endif (???)
endif (???)

There's a heap of variations to your algorithm (some already pointed out), but
we'll get nowhere (or go 'round in circles) until you clear up just what your
intentions are (especially if you drop in those 'end if' thingies)

If you do that, you may find out exactly what you're trying to do, and needn't
have posted this in the first place.

Two more things

One:

You don't seem to understand the IF structure

It's not
IF.. THEN.. ELSE..
it's
IF.. THEN.. ELSE.. ENDIF

Two:

If you're developing a program, DO NOT TRY TO MAKE ONE-LINERS for "IF..."
structures. You can do that later, once you've worked out your (correct)
algorithm, but then if you don't document it properly, you may be saying
"huh!! what was I trying to achieve" years later (months, weeks, days even)
SEPARATE YOUR STRUCTURE WHILE YOU'RE DEVELOPING.
You nearly have it right in your algorithm (toss in a few 'ENDIF's here and
there to clarify), but stuffed it trying to write a one liner
Leave that to the professionals (Google Rick Rothstein's amazing record of
one-liners for examples, but be prepared for some doozies)

I didn't clarify that all must be a single statement evaluation.

It follows all the If - Then execution except in the final evaluation it is
IF - Then - Else. My experience is it will never do the Else the way I wrote
it.

Is your response a single statement?

Thanks.

Why on earth would single line If-Then-Else statements EVER be a
requirement? Personally, I think such a requirement is, well, insane... and
you can see the reason why based on the fact that you had to come here for
help.

You also didn't clarify the logic tree so anybody could possibly infer
what is correct operation.

That happens w/ incorrect syntax.

> Is your response a single statement?

I'd _NEVER_ consider that as a defining consideration.

Do you want correct code or one line of code that may (or may not) do
the right thing?

Not very helpful and not very friendly. Just an opinion!

A simpler method for acheiving the goal of having no one respond to your posts
would be to not make them in the first place. However, behaving like an idiot
will probably also accomplish that goal...

By the way, you can fix your original single statement version by putting an
Else in front of the second If. Oh wait, you don't want any responses...

LOL!

You are a silly person and your reply is straight out of "Hitchhiker Guide",
as you managed to blow off the one person around here that is likely to
provide you with a reasonable solution.

Instead of being aloof and annoying you should have just answered a few
questions. Instead you are going to get equally silly answers like this one

[Watch for word wrap]
If Not VarName1 Then If VarName3 = "String1" Then Sub3 Else Sub4 Else If
