Where do the numbers come from listed on the balance sheet as Other Assets and Other Short Term Liabilities?
The definition of a balance sheet is that the assets must equal (or be in balance with) the liabilities. If the information you have entered results in an imbalance, the difference between the two will show up in one of these cells. This may be because you have entered an asset with no associated expense, or you may have entered expenses with no resulting asset.
