I'm doing a tutorial on CmiVFX and in one spot it calls for reversing out a previous Transform by referencing the channels of the first and inverting them.

The problem is, as soon as variables are used in the first Transform, the second one breaks and says it's a “bad data type for function or operation”

It doesn't work in the tutorial source files either, so I assume it's something that's changed with new versions of Houdini.

Does anyone know the way around this?

Thanks
