Extract data and put it in excel file or local data

Hi Boyan,
sorry for the late reply.
I encountered a few issues but figured that part out.
I think the page how to get/set variable is a bit vague.
I had the recorder extract that the text contains "string" and I wanted to use that string to be displayed in a messagebox.

object myData = GetExtractedValue("varname");

Object can be replaced with string or integer?  "varname" is where you have to enter the Databindvariablename?
if you cannot change the object to string or integer will you have to convert it to string? .Tostring?
