Hello,
1. You should contact the author of the formula. I am not the autor.
2. I was just mentioning the fact that backslash should be written as \\
(I did not check the formula for other errors - various people send formulas
here and you should contact the original author because I am not responsible
for other people's mistakes )
3. "Array subscript has to be a number" error means that the author of the
formula made the mistake (used a string or array as subscript)
4. printf output is written to:
- commentary window
- interpretation window.
Consult Users guide for more details
Best regards,
Tomasz Janeczko
