This is basic (I hope) but beyond the scope of my syntax understanding (which is built around 'swap pieces of text in and out until they work'.

Found this very handy script block on another post to administer remote commands to another vMix machine:

Dim client = WebRequest.Create("http://192.168.121.32:8088/api/?Function=AudioBusOn&Value=B&Input=Call_09")
Dim response = client.GetResponse()

Works great, and it's easy for me to figure out which vMix machine to point it at, and how to change the commands (that one sends Call_09 to Bus B on the machine at the .32 IP address, awesome).

How could I combine several of those commands into one script? So I want to send these commands to add Call_09 to bus B, and swap the vMix call sources to Output4/Audio Bus B:

Dim client = WebRequest.Create("http://192.168.121.32:8088/api/?Function=AudioBusOn&Value=B&Input=Call_09")
Dim response = client.GetResponse()
Dim client = WebRequest.Create("http://192.168.121.32:8088/api/?Function=VideoCallVideoSource&Value=Output4&Input=Call_09")
Dim response = client.GetResponse()
Dim client = WebRequest.Create("http://192.168.121.32:8088/api/?Function=VideoCallAudioSource&Value=BusB&Input=Call_09")
Dim response = client.GetResponse()

Obviously that block of text doesn't work or I wouldn't be here. Current error is Variable is defined without an As clause... but the single command doesn't need that. I've been fiddling for a while (different variable names, trying to get all the commands under one WebRequest) so I'm hoping someone can just fill me in on the painfully obvious thing I'm missing here as a result of just barely getting how Dim actually works in this syntax.
Thanks,

Much improvement. I had to make the additional client/response variables unique by numbering them, but this block now gives me no syntax errors. (Unsure if I need to also number the response.Close lines? Or are they just all purpose?)



And on testing it seems to do exactly what I need it to. Thanks!

One further tweak: I'd also like to add a single local command (Function=AudioBusOff&Value=A&Input=Call_09) to the script, but adding that in anywhere causes an Invalid Syntax on Line 1. I assume I can work around it with another WebRequest/Response block aimed at localhost or the local machines IP address, but in the interest of making it leaner, can that standard Function call exist in this script?
