Your question(s) are confusing. You ask about automating "the following script", but there is not a script, unless your picture of the display boxes is referring to the script behind the display boxes. On the automation, yes, you can use the Schedule() function to wait for a specific period of time and the run a script.
Concerning the pull down menu selection, it would be my assumption that JSL can query the lists that create the pull downs and from that get the information needed. But it would not be making the clicks, etc. in an automated script.
JSL is a very complete programming language, so you can pretty much make it do whatever you want.
