Max/Min expression invalid parameter

R78 32 bit win7.

Description: expression editor doesn't allow to set the second parameter (b) of max(a,b) and min(a,b) to a variable. It drops an error: "Invalid Parameter - Parameter 2 of 'max': must be a number"

This happens in any expression, not just in the "Set text" like the example.

Quick workaround, cast your variable in a float() or an int()

Oops, typo in the expression checker. Fixed for next build.
