Hi

I have a table which holds various details i need to count the amount of times an item appears.  But i need to only count the item against 1 id  - i think i'm confusing things - so here's what i need

Logid                  LogType                     Info
035621                  FILEH                       Log on
035622                  FILE                         Log on
035622                  FILE                         Check Something
035622                  FILE                         Log off
035623                  FILEH                       Log off
035623                  FILEH                       Log on
035624                  FILEH                       Log on



So basically i need to count how many times File and FileH appear against the Logids

So the result i need from this is

Logtype                             Count
FILE                                     1
FILEH                                   3

Thanks
