Trying to use Perl for the first time. I have put the code together from tutorials I have found on the Internet.I have a text file that has a entry format of wk,name,team If the person submits a new entry for the same week I want to over write the team value in the file. If it is a new entry the file updates fine but if there is an existing entry, the replace code isn't working for me. I read the small file into an array and then try to change the value if appropriate. I have just posted the snippet of code that isn't working. All the other functions the cgi does with the file are ok. The value of $surv is passed ok into this section but the replacement doesn't happen. I have verified the code is dropping correctly into this section but the record stays unchanged. I was just looking for more experienced Perl users to comment on what I was missing since the replacement doesn't happen. Unfortunately my perl experience is just reading tutorials and trial by error. 
@raw_data=<survdat>;
  foreach $survinn (@raw_data)
  {
 chomp ($survinn);
 ($survwk,$survn,$survtm)=split(/,/,$survinn); 
 if ((uc($survn) eq uc($poolm)) && ($survwk == $weekin))
   {
   s/$survtm/$surv/i;  
    seek(survdat,0,0);
print survdat @raw_data;                        
  }
  }
