I'm trying to use the 'formula node' to calculate cumulative lethality. the inputs are 'x' (temperature), 'z' (z-value), 'r' (reference temperature) and 'T' (elasped time). The error message 'variable undefined' isn't very helpful. I've included a snippet of the code. I would appreciate if someone could tell me what is not defined.
thanks

It was helpful enough for me to google this:

Does that help? I had a kind of hard time understanding it.

Whew! It was kind of hard for me to understand. I couldn't even translate it for you. I had to just post the link.
