This one is driving me bananas! I have a test in a program loop that goes like this:

while (Test<1)^(t1<tm)

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?

Yet again, using units has saved me from myself. There was a subtle bug elsewhere in the program that meant that "Test" was NOT unitless (as it should have been), so Mathcad acted quite properly in rejecting the comparison of Test and the (unitless) number 1.
