It sounds like you have a section break in your document, which is causing the dotted line and the page break. Here's how you can delete it:
- Go to the "Home" tab in the ribbon at the top of the screen.
- Click on the "Show/Hide" button in the "Paragraph" section. This will show all the formatting marks in your document, including section breaks.
- Look for the section break that is causing the dotted line. It will look like a double dotted line with the words "Section Break (Next Page)" next to it.
- Click on the section break to select it. You should see a gray highlight around it.
- Press the "Delete" key on your keyboard to remove the section break.
Once you've deleted the section break, the dotted line and the page break should disappear, and your text should flow normally. If you have any other section breaks in your document that you want to keep, make sure to leave them in place.
