Has anyone encountered the problem of assigning an input from a preview to a multiview of another input?

Code:
dim xml = API.XML()
dim x as new system.xml.xmldocument
x.loadxml(xml)

'writes the input from the preview to the WhatIsOnPreview variable
dim WhatIsOnPreview = (x.SelectSingleNode("//preview").InnerText)

'replaces the title text with the WhatIsOnPreview value. And it works
API.Function("SetText", Input:="TextHD.xaml", SelectedIndex:="0", Value:=WhatIsOnPreview)

'should assign WhatIsOnPreview to the first layer of the ColorBars's multiview. But it does not! instead, the layer gets the value None
API.Function("SetMultiViewOverlay",Input:="Colour Bars",Value:="1,WhatIsOnPreview")

You are trying to embed a string within a string in the function! that's a coding nono

you need to Concatenate them

Code:
API.Function("SetMultiViewOverlay",Input:="Colour Bars",Value:="1," & WhatIsOnPreview )

To answer that directly, yes. It's one of the early things I was looking to do. But, scripting is not in intermediate vMix versions and eats into valuable evaluation time, so I had to go another route.

Is this possible, without scripting?

On a related note (this one may be basic, but I'm not finding it either), is there a shortcut/non-script way to assign "None" (no input) to a multiview layer that already has positioning and an input in it's place? I've just made a transparent input and used a shortcut to assign that in the mean time.

one can always use external ways of scripting :-)
Check the API XML for the input that is in preview and replace the layer of the MV with it

Input,None seems more obvious to me, but I'll have to check if that can be done in Companion or need to change the shortcuts involved.

Blank, or leave it empty (= none lol) or any not specific reference to an input doesn't really matter does it ? They seem logical enough to quickly test with and find out if the word None didn't work

Turns out it was from doing it by way of Companion. Preview = 0 and PGM = -1. But it would have been nice that the documentation for that shortcut specifically notes a null input is permissible to narrow it down.

Incidentally, that also solves the issue assigning the PVW input to a queued set/multiview, then previewing the set without scripts or shortcuts.
