Adding string parameters gets me a <unknown> problem

[redliontrader]

If I want to add string parameters post wizard I am doing the following.

In the Variables region I add:

private string label = "NYSE"; // this is my new Parameter name.

In the Properties Region I add:

[Description("AD Line Name")]
[Gui.Design.DisplayName ("\t Label Name")]
[GridCategory("Parameters")]
public string Label
{
get { return label; }
set { label = value; }
}

When I go to the parameters to add and customize the indicator I get the following:

see attached image. Any help would be appreciated..

Thanks

Hello redliontrader,

I used your code snippet and did not see similar issue. I would simplify first with only one string input. You can also have the indicator wizard generate all the necessary code for these.
