Cannot record a selection from a drop down list

Hi

This is my first time recording an automated test using Telerik, I am recording a click on drop down and then selecting a check box in that list of values.
When i playback, this test step is failing. Can you please suggest a way on how to record this or if i have to add some code in order to record the above
function
 Below is the error i am getting when executing
