  A1 --> B1

  A2 --> B2

  Count B = 2

  A1 --> B1 --> C1

  A1 --> B1 --> C2

  A2 --> B2 --> C3

  Count B = 3

  What I mean : Row 1 in A joins to 1 Row in B and 2 Rows in C. Result = 2 Rows, duplicate A, duplicate B

  Not the only possibility, but likely.

  ;p)

  Edit: Oh and use the Alias "A" - you declared it after all.
