Visual Studio dll referencing NT7 Indicators

I'm in the process of packing my custom indicators into an external dll using Visual Studio. I've gotten a few methods to work with help from this site (much appreciated) but I can't seem to make a call to any NT7 indicators. For example, the line...
 
Code
double avg = SMA(Input, 10)[barsBack];
gives me the error Error 'NinjaTrader.Indicator.SMA' is a 'type' but is used like a 'variable'
Does anyone have a clue as to what my problem is? Thanks in advance.

Remove the bars back. It is not needed for the SMA.
In the Ninjascript editor if you hover your mouse over the SMA it will tell you what parameters are needed for the indicator. In this case it is: int period If you need a dataseries then you can add input as the first parameter.

What are you trying to accomplish with the [barsback]

I have the following function I'm trying to offload (along with others) into a single dll that I can reuse in other Indicators and Strats. For this one, I'm getting a general direction from which way the market is entering my defined support level. I know this can be done other ways, but I would like to know how to make the NT7 indicators work as well in Visual Studio. (This function works flawlessly in all of the indicators I have used it in.)
 
Code
/// <summary>
/// Given: barsBack is the start of the first signal. support is the price level of the potential support
/// Returns: -1 from below, 1 from above, 0 otherwise
/// </summary>
/// <param name="barsBack"></param>
/// <param name="support"></param>
/// <returns></returns>
public int IntoSupport(int barsBack, double support, NinjaTrader.Data.IDataSeries Input) {
     i = new NinjaTrader.Indicator.SMA();

     double avg = i.SMA(Input, 10)[barsBack];
     if (avg < support) return -1;
     if (avg > support) return 1;
     else return 0; }

I just downloaded VS_NTSampleProject that was posted by shodson. I think it's posted here, but may be on NT website. Sorry I can't locate the link. Scott Hodson (shodson) has two great webinars here on BigMikes that finally address more advanced topics. Hope this helps.
