How do I submit these records without having them disappear?
The only ways that I know that batches disappear are if they are not done by the Due Date or if a project is pulled altogether. My Due Date on both batches is July 23, which is actually midnight, GMT (Greenwich Mountain Time). My time zone is Central Time, which means they are due by 6:00 pm July 22. If the batches you have checked out are not submitted by then, they will be put back into the queue for another indexer to find and submit. Now, very rarely will a project be pulled. We've had some on-the-fly adjustments lately, but nothing that has warranted a project to be pulled.
In order to submit a batch, you can do it a few ways. The first is to click on the airplane icon, then follow the prompts.
The second is to go down to the bottom of the Entry part of the screen to where it says Do you see any more information on this image to index? There are two choices. Yes, Create Entry X. X could be Entry 2 or 3 or 1,350,012 (ok, not that many, but I did had over 300 entries for one image multiple times in the US Directories days). The second option is No: Submit Batch. Click that one and follow the same two prompts as option one.
The third option, I've never used, since I'm so used to using the airplane, but you can also go to Batch (next to the tree on the upper left), then go to Submit Batch and again, follow the prompts.
The prompts won't spell check for you, or tell you how many more entries you need but they will catch fields that are left blank, but are not marked blank and years like 19021, when you meant to put 1902.
