Your main problem is that the '' in the unlink line don't evaluate the variable.

You need unlink $FileName in the last line.

It will tell you how many files it deleted, and you could report this. 

sub DeleteFile()
{
   my $FileName = $_[0] . $t;
   $ret = unlink $FileName;
   die "No file called [$Filename] deleted\n" unless $ret == 1;
}

or, more concisely 
sub DeleteFile()
{
   my $FileName = $_[0] . $t;
   die "No file called [$Filename] deleted\n" unless 
      unlink $FileName;
}

Update: added third option.

or, you can be more friendly and return the value to the caller : 

sub DeleteFile()
{
   my $FileName = $_[0] . $t;
   my $ret = unlink $FileName;

   warn "No file called [$Filename] deleted\n" unless $ret;
   return $ret;
}

Which of the last 2 to choose depends on how important it is that the file is deleted or whether you have already checked its existence.
