Substitue value at index
Im looking for a custom function which enables me to substitute a value in a value list at a given index position. I found this one: http://www.onepartharmony.com/custom_functions_one_function.php?function=31 though i keep getting an error messages when i try to define this function. I guess there should be another function flying around on the internet but i cant seem to find any.
Thanx in advance
