Hey,
You’ve made a couple of simple mistakes which have caused those errors. I have attached a screenshot, compare and execute the same to get the output.
Check your digitalWrite command, it must have single quotes and the W must be capital, also check your url and twilio code which has the wrong variable attached to it.
