Upper case parameter

[ct]

What is the syntax to get a parameter entry to convert to upper case? I am entering a multiple instrument list. It works fine but would like to convert it to upper case where it shows in the parameter prompt.

This is what I have:
[Description("Markets to include")]
[Category("Parameters")]
public string[] Markets
{
get { return _markets; }
set { _markets = value; }
}

Ninja doesn't like: set { _markets = value.ToUpper(); }

What is the error message?
