[amibroker] McClellan Osicillator and Summation Index

[M. Dawson]

I am new to this but for some reason, downloaded both indicators into Amibroker 
and unlike every other indicator I have, it came up with empty on the ^GSPC.  
Am I missing something.  Does it work with another ticker that follows the SP.  
I don't know.  Need this to work with the S&P 500 for several of my 
daily/weekly checks.  I need your help.  Thanks____
