### Warnings

I get warnings when I try to merge data from a single survey made on two different computers.

The most common reason for warnings is that your hospital definitions are not identical in the two databases. In such cases you will get a warning message, but you will still be able to merge the data. If you are sure you are not going to lose data, you can go ahead and merge. In these cases, HWN discards the second hospital definitions and uses the one in the database you are merging data into.
