Word Documents: How to Fix Reference Source Not Found

1. Click 'Edit' and select 'Undo.' Alternatively, you can hold down 'Ctrl' and press 'Z' on your keyboard or click the curved error pointing to the left on your toolbar at the top of the screen. This engages Word's 'Undo' procedure. If you have not done anything else since deleting the field, the deleted field will come back. You can repeat the 'Undo' procedure for up to 10 edits in a document.
2. Print the document and look it over. If there is a section that looks strange on the printed page, displaying numbers and symbols rather than the text you typed, that field is causing the error. Right-click the field in the document and select 'Refresh Field.' Print the document again. If the document is correct, you will not see the error again.
3. Place the cursor inside the field and press the 'Space bar' to place a space in the field. This will make the program think that the field is completed and the error will not appear.
4. Right-click the field and select 'Properties.' In the dialog box that pops up, set the field default as:{Ask Answer 'Question' \d ' '}This will allow you to proceed with a blank field and not receive the error.
