receive warnings in customizer

When I click on CUSTOMIZE in my Highend theme dashboard – I get the following warnings:
Warning: Creating default object from empty value in /home2/fordbolt/public_html/wp-content/themes/HighendWP/admin/theme-customizer.php on line 15

Warning: Creating default object from empty value in /home2/fordbolt/public_html/wp-content/themes/HighendWP/admin/theme-customizer.php on line 16

Warning: Creating default object from empty value in /home2/fordbolt/public_html/wp-content/themes/HighendWP/admin/theme-customizer.php on line 17

Warning: Creating default object from empty value in /home2/fordbolt/public_html/wp-content/themes/HighendWP/admin/theme-customizer.php on line 18

**AND BELOW THE LINE IS THE REFERRED TO FILE (you can readily see which 4 lines are 15-18) I don’t understand what is going on. I set the color manager to color customizer in Highend options, and filled in my title, tagline colors and background.
