etc. Test is unitless. t1, tm are in seconds,and the ^ is the AND symbol from the Boolean toolbar.
As a standalone line (Test<1)^(t1<tm)= it works fine.
But in the program segment mathcad insists that the units of the (Test<1)part do not match. It used to work fine in Mathcad 2000. I am now using Mathcad 11.
Has anybody got any suggestions?
