Counting Varies Depending on Multiple Choice Selected

Instead of [Tubs Needed]="NONE", try this:
Contains([Tubs Needed], "NONE")

As you can see, the formula "sort of works" so we are closer :)

Screenshot #1 
Is the [Tub Count] Formula Field, it is a Formula Numeric Field - you can see the current formula I am using

Screenshot #2 
This is what the Tub Count is summarizing/counting.  If user selects NONE then I need 0, any others are selected then I need a count.  

Screenshot #3
The report, the last two columns on the right, Tubs Needed and Tub Count.  The NONE argument returns a 0, YAY! This works just as I want,  the second argument should COUNT every letter, instead I get a number 3 no matter how many letters are selected.  

Please help.

Yes, I tried but, I may be doing something wrong.  It returns this error.  I thought maybe because it is not expecting the multiple choice textlist?

Because you are using a text list, you have to do some mapping.
Try this:

var number a = if(contains([Tubs Needed], "A"),1,0);
var number b = if(contains([Tubs Needed], "B"),1,0);
var number c = if(contains([Tubs Needed], "C"),1,0);
var number d = if(contains([Tubs Needed], "D"),1,0);
If(
    contains([Tubs Needed], "NONE"),0,
    $a + $b + $c + $d
)

GENIUS! That worked :)
Thank you so much, especially for your patience!
