Field only visible if multi-select field is one of three options

Question

Hello 
 I am trying to create a field that is dependent on a multi-select field that will only show if the multi-select field contains one of three options. 
 So if the multi select has the options of A,B,C,D,E,F. I want this new field to appear if that multi select contains A,C or F. 
 Now the multi select may have more than one selected or one of those three and more options as well. 
 Examples of the multi select could be A,B,C which should show the field. Or B,E,F which should show the field or D,E which should not show the field. 
 As long as one of those three is select no matter how many others are I want this new field to appear. 
 The formula I have so far looks like this 
 isInList("A",createList($multiselectfieldexample)) 
 
 This works just for option A but I would like to add the other options into this formula. 
 
 Any help would be appreciated.

Hi Jarod Teixeira , 
 To check on whether there are different values selected, you will want to use an or() formula to check for each value. The formula based on your example of keying off values A, C, or F would be: 
 or(
 isInList(
 "A",
 createList(
 $multiselectfieldexample
 )
 ),
 isInList(
 "C",
 createList(
 $multiselectfieldexample
 )
 ),
 isInList(
 "F",
 createList(
 $multiselectfieldexample
 )
 )
)
