Hi. Not sure what the problem is. I assume you can make the jString(n,r) function work. If not, I will check the code, but it works fine on my PC.

If you have problems with making a chart, then, I don't know what outcome you are trying to get. The output of jString is just a string of the LaTex maths symbols which will display a FGH function on a blog.

Hope this helps.
