Unable to Compile Strategy using Donchian Channel Indicator

[Lmnop]

I am using strategy builder to make a strategy using the Donchian Channel Indicator. In order to eliminate variables I have reduced the strategy down to the following conditions and actions:

Default input[0] > DonchianChannel(14).Mean[0]

After hitting the compile button an error window pops up that reads "Could not compile NinjaScript". I'm don't think I am doing something wrong, and I know there are some other indicators that cant be used in NinjaScript, but after searching these support forums, it seems others are able to use the Donchian Channel indicator with strategy builder.
