Slider problem

Go to Media Library, click on edit for a particular image, then under it press the “Add to Slider” button.

Yeah i have done So! But at the bottom of the edit screen of any image i see the message “You haven’t create any slider yet. Write a slider name and click on the button to add you first slider.” before the “add a slider: button.

This message appears below Option “Choose a slider”

There are 3 items below ‘Choose a slider’:
1) –Select a slider–
2) blank box
3) Add a slider button

You need to enter a new slider name in 2), then click on 3). Once you’ve done that, the slider name will be available.

Now i have added the slider, following the steps.
and selected the slider in the theme options as well, but still the demo slider is shown.

if you want your new slider on Front page you need to set it. Go to yoursite.com/wp-admin/customize.php , tab “Front page”. Find Slider options >> Select front page slider and there you need to select your new slider. After that click on “Save and Publish” button and you are done. Refresh (Ctrl+Shift+R) your site and you should be able to see your new slider in action

Thanks all of you guys!
Done!
