i corrected the "if params[:exp] == '1'". but i want to save the input got from the radio button to an variable so that i can compare it with another string and with the result of the comparison i need to increment a count variable SO so i thought i ve no other way other than global variable to use it across views and controllers.But even when i tried the $ way ,@@ way @ way , when I assign params[:exp] to it it is not getting displayed.Kindly suggest me a alternative solution.
