Guess you will have to be more specific in describing what you are doing and which kind of table you'd like as result.
I would probably help, too, if you attach your worksheet instead of showing just one single line of calculation.
Also we don't see the arguments you call you function chord_lenght with.
I fear that you use range variables to do so which is not the correct way to do but thats all kind of reading coffe grounds without seeing the sheest.

Please attach your Mathcad worksheet to the message by using "Use advanced editor".
Is this what you're after?
