Topic:
Error: Source or destination horizon is missing SNAP attribute.

Description:
User gets the following error when trying to merge horizons in Seis2/3DV > 
Areal > Multi-horizon Merge:

     'Source or destination horizon is missing SNAP attribute'

Solution:
This is a bug in GeoFrame 3.7 and 3.8 and occurs when the top horizon has more than 7 attributes associated with it. Workaround is to delete the extra attributes. 7 attributes or less works.

Alternatively, can merge the horizons together by using Basemap > Tools >
Horizon operations > Multiple.
