Here is a copy of the snippet I am working with. I want to be able to choose from the list based on what I did with my client. When I fired it off, nothing happens 
@Ricki_Gillespie this is what I consider to be one of the more confusing things about toggle fields. In your example, all of the toggle fields have a name applied, but they don't actually have any content inside of them. Since the names of toggle fields are never added to the final snippet contents, that snippet isn't generating any text at all. You need to add the name as the content of the toggle field as well for them to generate any text. Updated just a few here for example:
{formtoggle: name=Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V); default=yes}Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V){endformtoggle}
{formtoggle: name=Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV); default=yes}Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV){endformtoggle}
{formtoggle: name=Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (WPPSI-IV); default=yes}Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (WPPSI-IV){endformtoggle}
