Net Module Rule 9:400

[MarkJames]

So if I send myself an elk variable using  an email customization it works fine.  Something like ${elk.zone.1.name} - I can send that to myself with no problem

But if I send the same thing via network resource it fails with a 400 error.  I can send ${var.1.1} but if I send ${elk.zone.1.name} I get a Net Module Rule 400 error.

Any idea why? 

To send variables I have to leave URL encoding off.  If I turn it on then it sends the text ${var.1.1} instead of the value of ${var.1.1}
