I'm having the following issue on Mathcad, I want to create an iterative index to calculate the values on the table, but can't, any idea on how to solve this?

It doesn't like your evaluation of n, so delete the equal sign at the end of the assignment

you need to put a place holder for the column like l[n,k

Should work if you follow IRstuff. Just type n:=1..15 without following '='

Statement n:=1..15= converts range 'n' variable into an array, which cannot be used for indexing. See examples of PTC. Mathcad 15 is not different in this respect:

I don't know how to mention users, but thanks @yakpol and @IRstuff, i initially thought that @IRstuff was referring to the equal sign at the end of second assignment, thanks also @yakpol for your lengthy explanation, thanks also @structSU10
