+## Unexpected unsaved changes error
+
+When working on forms, you get the *unsaved changes* error on the form footer, when you navigate from the current form, or when the form is getting saved without any changes. 
+
+**Resolution**:
+
+The *unsaved changes* error appears when a change is made on the form and when the changes were not saved. If you haven't made any changes manually, they could be coming from a JavaScript, plug-in, or from a business rule. You can use [Monitor](../../maker/model-driven-apps/monitor-form-checker.md) to view the `UnsavedChanges` event that helps to find the source of the changes. You can filter by OperationType `UnsavedChanges`.
+
+The `all attributes modified` section includes a quick summary of the columns that are causing the unsaved changes error along with their values. The `unsaved changes` section shows what happened to the columns in detail. For every column, a list of controls are provided that could be causing a change. The value change is also displayed (previousValue, newValue), as well as a call stack.
+
+The screenshot below shows the root cause of the issue. You can see that the change has come from the `OnLoad` script.
