If you are entering hymns for something other than a sacrament meeting please indicate by checking the appropriate box at the bottom. You only need to fill in a field if a hymn from the LDS Hymnbook was sung. (i.e. If no rest hymn was sung, leave it blank. If the closing hymn was from the Children's Songbook, leave it blank.) The "Other" field is for special musical numbers.
The location is optional, but it may help to look at regional variations.
