Compiling errors on a default ninja script that works?

[BroX8]

While working on my own script, I pulled up the Constant Lines script posted below to see particular language. I did not change anything. I just compiled it and I got these programming errors. However the script works. I have it on a chart right now. It works great despite these errors. It just so happens that these 'labled lines.cs errors are what Im getting to. Why does the default ninjatrader script for 'constant lines' have errors yet it works?

Hello BroX8,

The errors in the image are not for the code you posted, the errors relate to a script called LabeledLines.cs. You can see which file the error belongs to by looking at the filename column. If that is an indicator you should be able to remove it or exclude it by right clicking on the file in the editor and choose remove or exclude from compilation.
