Ah k, in cases where you want to print out a value only if it is 'blank', you want to test for a defined value rather than a blank one: 

print "<th>$WasonE{HSName}</th>\n"
    if ( defined( $WasonE{'HSName'} ) );

This will get rid of the warnings you are seeing in your log file, though this will not fix any actual errors. When you run the script in the browser, does it still work as expected, even though you have a lot of warnings in the error log?
