On the OPC Item Path have you configured them to be expressions that link to your parameters.
It looks like the first has no path and has errored while the second you’ve selected the OPC path correctly.
Okay, I figured out what the issue was, If the parameter name contains a - then the value does not get passed through. This has to be a bug that needs to be fixed.
Just make your parameter names (and any other names) in Ignition follow the typical rule for variable names in programming and you will be fine. (Alphanumeric plus underscore, but no leading decimal digit.)
