Select data from one row, while on another row in the same table. - response (10) by TDW

Thanks Dieter. That stopped the 3706 error. Now I have another. "2666 Invalid date supplied for NJSHoliday.Holiday." Below is the full code I am runnning. I am posting this here now (so I won't forget later) and will continue to troubleshoot on my own. I will post if anything changes.
Thanks again for your help; I'm learning a lot.
