How to call other indicators from code

[cassb]

I need one indicator to get the value of another one in the OnBarUpdate code. I'm having trouble with a particular (licensed and locked) indicator that keeps returning 0 as its value.

I can get values from these other indicators:

Standard indicator EMA(9)[0].ToString() = 1.33744268334864
Custom indicator SAFqt(9)[0].ToString() = 1.33678766781693

but this indicator returns 0 every time:
MA_Multicolor(2, 30, mAType, 30, 9)[0].ToString() = 0

This is a moving average indicator like the other two. I can't look at the source code because it's licensed. But I should be able to use the above statement to get its value, shouldn't I?
