EDIT: Got it to work after some fiddling. Sorry to bother.
Hello, this will be my first post. VERY new to JavaScript and require a bit of assistance with the code below.
Once I add an option value 3, the second drop down will not generate for option 3 after entering options in SList.slist2 and SList.scontent if options are entered for option 3, the second drop down list stops generating all together for option 1 and 2 as well. I would appreciate any feedback. Thank you!
