Finding errors isn’t that difficult. Browsers will popup a box that tells you there is an error, and in most cases, will even tell you what line that error is on. Simply count down the lines from the top of your document, and include blank lines when counting to find your errors. You may even see multiple errors at one time on that error popup. If this is the case, start at the top and fix each error as you find it, and then run the script again after each fix. Often, one fix will correct numerous errors.
