User Input During Report Generation.

Hello,

I'm trying to do something simple that has turned out to be a frustrating problem. I have a field in my report that needs to be populated by user input. Based on this user input, I will use the field in a calculation. The simple solution to me, was to create a custom assembly that has a function that uses Console.Write("Input Data") and Console.readline() to assign the input to a string, and then return that string to the report. This works fine in a test console application, but when I copy and paste the code to my custom assembly, it returns #Error to the report. I've debugged, and found that when I hit F10 on Console.Write("test"); it skips right over it, and nothing happens. It also skips over Console.readline(); with nothing happening. This makes me unable to take the user input and set the textbox equal to that value.

Am I doing this completely wrong? Is there something I'm missing, or just not understanding correcly? It seems like reporting services has to have this option. I'd really appreciate some advice. Thanks!
