i'm getting an error for $! as "Resource temporarily Unavailable". I'm trying to write to a file using Spreadsheet::WriteExcel's write(). The $worksheet object is defined at the top of the file, but when I hit the below while loop, it won't write() and puts RTU in the $! variable.

I don't think it's a scoping issue because the $worksheet object is defined well before the while loop. My query for the information that needs to go into the doesn't choke, so I'm not writing with uninitialized variables. Would appreciate your opinion.

# At top of file
my $workbook = Spreadsheet::WriteExcel->new($target);
my $worksheet = $workbook->add_worksheet("Ventus_Networks_Invoice");
my $row = 0;

...

# This is the header row, that prints
 if( $qrv > 0 ) {
       my $mid_header =
$workbook->add_format(%oUpper,%iLeft,%iRight,%greybg,%fBold,%iLower);
       my $mid_theader=
$workbook->add_format(%oUpper,%iLeft,%iRight,%greybg,%fBold,%iLower,%f
+Twrap);
       $worksheet->write($row,0,'Site
Name',$workbook->add_format(%oUpper,%oLeft,%iLower,%iRight,%greybg,%fB
+old));

...
# After headers are printed, print data
 while(my @i = $sth_site->fetchrow_array() ){
           $worksheet->write($row,0,$i[1],

$workbook->add_format(%oLeft,%iRight,%iLower)); # Location ID
# This is where $! is set to "Resource Temporarily Unavailable

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
