Virtual pin value as parameter in eventor

Hi.

I have a question about using a Virtual Pin Value as parameter in a event in Eventor.

Example:
A have a Level V Widget, and i want to set the “max parameter” with a “numeric input” widget.

I try to use the eventor, to create a rule for this. [ When “numeric widget” is changed set pin "level v property max to ???]

How can i put in ??? the numeric input value?
