Hi Mukesh,
Can you please share the image of the particular part, where you have the confusion?
Hi, it looks like you are using a different version (Mx 10.6) than what is expected for the Crash Course (10.0.0). This means that in some cases, the standard behavior will be slightly different. I would recommend you use the suggested version for the course to be able to follow it completely.
i changed the control to inut refrence set selector and showing option for select Page now.. somehow when i created it was added as combo box , did not see instructions to change it .
