Hi Michael:
For doesn't contain you can use
If(Contains([Channel Summary], "Retail Sales and Distribution")=false, "some value")
Formula for Formula Multi Select Text Field:
Split(
If([Channel Summary] = "Retail Sales and Distribution"), "Retail")&";"&
If (Contains([Channel Summary], "Retail Sales and Distribution") or
Contains([Channel Summary], "Tech Care - Mobility") , "Omni", )&";"&
If(Contains([Channel Summary], "Retail Sales and Distribution")=false, "some value"),
";")
I hope this helps :)
