I am learning and following this tutorial…

When I add the response to parse the data it throws an error. I am sure I am doing something very silly, but could someone help me out?

Drop that orange ‘set’ block into the “when get is done” area. “response” only works within the purple block. (It’s not a global variable.)

It’s also important that you run blocks within the “then do” section if you want to be sure they run **after** the Web API “Get” call runs. Otherwise, the Get call may take a few seconds but Thunkable will continue to run blocks after that (such as the _set app variable advice_ block) immediately without waiting for the call to finish.
