I am trying to use some simple logic in a script (using Dynamic script) that would allow a single X-Key button to both initiate the merge and then remove it. I'm not a scripting expert, but would like some pointers (even if I put this as a script call, that would help). Below are the two current scripts and the third is what I'm trying to do. Any pointers?
Thanks

This script sets the 'DynamicInput2' to the camera input selected (Sleep is to allow PTZ movement).

Function=PreviewInput&Input=Cross above altar
Sleep 1000
Function=Fade
Function=SetDynamicInput2&Value=Cross above altar


This script sets the layer using 'DynamicInput2' for the selected camera and then performs merge of the music (did not seem to work without Sleep before the merge function).

Function=SetLayer&Input=LambofGodMV&value=2,Dynamic2
Function=PreviewInput&Input=LambofGodMV
Sleep 100
Function=Merge

The above scripts require the button press to perform the MultiView but then must use a separate Merge button push to remove. Trying to add use of DynamicValue4 to set to 0 upon camera select and then set to 1 when the multiview is selected. Then if multiview button pushed again use Merge only. Must reset value to 0 when MV is removed as there is another MV used a little while later. This does not work as is, but the concept is there.

If DynamicValue4 = 0 then
Function=SetLayer&Input=LambofGodMV&value=2,Dynamic2
Function=PreviewInput&Input=LambofGodMV
Sleep 100
Function=Merge
Function=SetDynamicValue4=1
else
Function=Merge
Function=SetDynamicValue4=0
end if


Need to add the following to the each Camera Input Selection script:
Function=SetDynamicValue4=0

Thank you for the input. Here is what the Layer/Multiview looks like when in output:

The music portion is selected from another input and the camera is also selected. Once the operator
selects the camera (in this view the cross is the placeholder for the camera which is stored in DynamicInput.
The when the shortcut for the multiview is pushed, the camera is loaded into the MV and then the preview is
merged into the output providing the small view of the camera with the music showing. When the music is done
the operator now pushes the merge button, but what I'd like to do is have the same button pushed to merge back to
the camera view. There is another music selection later with the same type of view.

The view is not too complex but as I'm learning more scripting, this one has been a bit of a challenge as it
includes IF THEN ELSE type logic. Where a Dynamic value is used to store the current state of the view.

Hope this explains it a bit more.
