Invoke tWebserviceInput with ArrayOfString

[Anonymous]

Hi,
I'm trying to invoke a web service that requires a parameter of a type ArrayOfString. Does anyone know how I can do that with tWebserviceInput? I tried using an array in the parameter but I got an error, I placed the values:
Parameters:
"{"1","2","3"}"
Can anyone help?
Below is my WSDL:
<?xml version="1.0" encoding="utf-8"?>
<wsdl:definitions xmlns:soap=" http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tm=" http://microsoft.com/wsdl/mime/textMatching/" xmlns:soapenc=" http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime=" http://schemas.xmlsoap.org/wsdl/mime/" xmlns:tns=" http://www.mysite.com/AppServer" xmlns:s1="
