There are many indications symbol in the code of LED its saying expected doctype not found,unexpexted end tage etc… how to solve that error
Can you post relevant screenshots and code you are facing problem with?
Your code looks alright to me,
Check your led connections whether you have connected positive end to digital port 0 and negative end to ground properly.
Check whether you have enabled Api Key. You can do the same by clicking on API icon on the left side of your Bolt cloud dashboard.
