TI-Basic: Nspire Basic Function will show Too many arguments

Question

I am currently struggling with TI-Basic. I am using a TI-Nspire CX II-T CAS and I want to write my own library and add some functions for statistics.

But at the moment I can not get to work any funcitons at all. Even the most basic code will not work. What I did was:

1. Add a new Programm named "cube" type "Function" and Library Access "LibPub"
2. I have written the following Code

Define LibPub cube(n)=
Func

Return n^(3)
EndFunc

3. Saved it on my PC
4. Copied to Hanheld's MyLib
5. Refreshed the Handheld's library Docs --> 6
6. Open the Library and Call the Function that will look like cube\cube(5)

Then I get the Error Message: "Error: Too many arguments"

Does someone know where I made the mistake?

My Goal before was to do a function that will take function(n,k) and return the value of n!/(n-k)!. I mean both should be pretty straight forward. I hope someone could help me wasted already more then 6h on this...

Answer 1

Found out what it was. The Code was not the problem. The problem is that CTRL+S will save the document but not the function. So if you want to Save it you have to first press CTRL+B and then move it.
