Can someone send an example of a “PARAMETER BINDING”  
I have a UDT that where I want to bind the value of a tag to the metadata of a tag in the same UTD.

I want to bind the value of a tag named “20ma” to the “ScaledHigh” of tag “AMOUNT”.

should grab the scaled high from the UDT instance Amount tag.
