I was having problems getting ACTUALS to show up in a monthly budget report. The category was showing up on the report, the BUDGET amount was showing, and an (incorrect) variance/difference was showing, but NO ACTUAL was showing - the actual showed up only as $0.
After much trial and error, I discovered the problem resulted from having parentheses in the NAME OF THE CATEGORY. That is, when my category was named "Sunnyslope (net)" no actuals were reported - but when I changed the category name to "Sunnyslope - net" the report worked properly, showing the actuals, the budget, and the correct difference.
