I have a test case where I am iterating using a FOR loop, where the variable in the loop is "j". 
I am then using this "j" in a user-defined keyword, but the test case fails and the error is "Variable j not found".
This exact same test case works on another machine without any error, and I'm not sure why. In my machine where it fails, there is no problem with libraries or the setup, and this variable is not being saved anywhere.
Could someone please suggest why this could happen?
You can give variable "j" with symbol @
