 I am trying to create a %True indicator in TC2007 using the formula:

(100 * (C - MAXH10) / (MAXH10 - MINL10)) > -25 AND (100 * (C1 - MAXH10.1) / (MAXH10.1 - MINL10.1)) < -25

The indicator should show me when the calculated value crosses above -25.  The calculations work prefectly on a spreadsheet and should show 100% when the condition occurs.  

What am I doing wrong that I get an error that this formula is not a Boolean Formula.

I appreciate the help.

 Your formula would probably work in TC2000 version 12, but TC2000 version 7 doesn't understand the -25 as written (it sees it as subtraction instead of a negative sign). You need to either put it in parentheses:

100 * (C - MAXH10) / (MAXH10 - MINL10) > (-25) AND 100 * (C1 - MAXH10.1) / (MAXH10.1 - MINL10.1) < (-25)

Or subtract the 25 from zero:

100 * (C - MAXH10) / (MAXH10 - MINL10) > 0 - 25 AND 100 * (C1 - MAXH10.1) / (MAXH10.1 - MINL10.1) < 0 - 25
