Subject: Not Passing Array - msg#00001

Hello all,

I'm trying to use a modified version of the nuSoap examples to connect to a SOAP server.  Based on exhaustive testing, I am 99% sure my code looks right, but for some reason it doesn't look like the array values are being passed.

Can someone please take a gander at the info below and help determine if this is a client (re: my) issue or the destination server?

Thank you so much in advance for any help anyone may be able to provide me!

- John
