Jlenia, We don’t currently have a general “Error Occurred” block for Thunkable X. However, many of the blocks which may cause errors have the ability to detect errors which occur during their execution and will return an ‘error’ value which you can test. Is there a specific block (or blocks) that you are interested in detecting an error from? -Mark ---
