To be honest, you are likely to find more timely help if you asked on the support forum (assuming it exists) of MathCad. I'm not sure how likely you are to find an answer here, but good luck. – Willie Wong Jan 25 '11 at 23:16
Is this on topic for our site? (I'm not saying it isn't. I'm just asking.) – Pete L. Clark Jan 26 '11 at 0:26
@Pete: according to the FAQ, it is. Last bullet point of questions welcomed is "softwares that mathematicians use". – Willie Wong Jan 26 '11 at 15:42

Mathcad "reads" down and right and you have defined the equation above the variable definition. If you drag the equation down it will work.

If you are going to be using Mathcad regularly, you might be interested in joining the Mathcad User Community:

welcome to Math.SE, and thanks for providing the solution! I hope you will continue to visit every now and then as I'm sure more Mathcad problems will pop up as the site gets more popular. – Willie Wong Jan 26 '11 at 15:45

There are two types of subscripts in Mathcad:

the text subscript (.) and the mathematical subscript ([)

you must use C.t when you define the variable
