Good Day, My empty reports problem as been resolved, however, I am drying to dig a bit deeper into the site-report script error. An error is thrown if the script is run with summary\_only variable is set to 1 (default.) There error says there is an undefined value as a SCALAR reference. While the error can be avoided by setting the summary-only variable to 0, you then will not get full reports generated. The error seems to be that several variables containing the reportable data are not set due to the if-statement on line 492. This if statement sets variables (header, incident\_summ, incident\_details, system\_summ, scan\_summ, signature\_distribtution) only if summary\_only is set to 0. I do not see any reason for this if statement and upon removing it, I am able to get full reports rather than just the summary. Does anyone who is more familiar with this script know why that if-statement is there and if removing it will have any negative consequences? Cheers, Edward ---
