Hi all, I am using SpreadSheet::WriteExcel, and was wonduring if there is a function under that module to do loop. the problem I am runnig through is: my first worksheet contains a lot of datas like in sheet1 I have the following : 
  FileName      ErrorType
  one.cxx          588
  one.cxx          588
  one.cxx          588
  two.cxx          333
  three.cxx        588
  four.cxx         666
  four.cxx         666
  five.cxx         588
  six.cxx          666

and I want in my sheet2 to have a summary like that 
  fileName          Error    588     333       666
one.cxx                       3  
two.cxx                               1  
three.cxx                     1
four.cxx                                        2         
.

where # 3 under the the error 588 indicating , how many times , that error occured fo the file one.cxx.

so basically , I am scaning the second column in sheet1 and counting the occurence of each error and display how many times it occures for each file in sheet2. Is there a trick to do the loop using the module, if not can someone give me a hint in writing that excel formula :(.

Thanks
