Dear all,

I am an ArcGIS newbie so please forgive me for this basic question.

I am trying to measure the shortest distances between a set of 15 origins and a set of 148 destinations along a road network.

When I load the locations for the origins and destinations and select solve, it only return 65 lines.  I want to know the shortest distance between each origin and each destination i.e. 15 x 148 observations. 

The analysis setting specified is 'cost' which I set as the field that measures the length of each road in the network when I created and built the road network dataset in ArcCatalogue.  What am I missing? 

Any insight appreciated.

Thank you.
