I have been trying to establish a relationship like the one in this example. I want to a record from a Look up field and fetch records from another Form and into these records into fields of the Same type and Name as the related Form.  i am using script with my form and app names that looks like this: 

string externalapps.GetType(int name)

{

    if (Enrollment_Information[ID == input.name].count()  >  0)

    {

        return Enrollment_Information[ID == input.name].Dog_s_Name_1;

    }

    return "";

}

i entered that code into the Create New Function area.

Then i entered:

input.Daily_Credits = paws-to-play.externalapps.GetType(input.Dogs_Attending); 

Into Dogs_Attending field>On User Input 

but it is telling me that GetType is not a Function.

So im COnfused....Help?
