NuSOAP client w/WSDL not returning value

Hello,

 

I'm having trouble getting my server to return a value to the client. Perhaps someone can look at the code below and suggest what I am doing wrong. All the function does is return true. Unfortunately, nothing is being returned when I execute the client.

 

Thanks,

 

Andrew
