Cursor SQL 2012

We are currently load data to tables from a spread sheet.  The first table to load the "master"  is a one to many relationship.  To start we have a cursor that grabs the items to load.  IT then loads the master table inside of that cursor is another that pulls the many columns to populate using the ITEM from the outside cursor.  The inside cursor only runs one time and exits?  We pass it the item value from the outter cursor, the inside cursor pulls 8 values, for the ONE item value, but it will only load the first pass and exit.  

I am not real good with sql, so why doesn't it run the full eight times and then exit.  (Some will have as little as five runs)
