I use Tex maker. I used the undo button until I got back to where I thought I clicked on something by mistake, then I clicked in the column where the numbers are. Apparently, there is a minus/plus sign that appears to be able to show/hide an equation, figure,...code. I clicked on the plus sign, and ...

In my document, I think I clicked on something by error, and all of sudden, 5 of the line numbering have disappeared!

I have something like this.

229 stufff
230 stufff
235 stufff

Any idea on how to fix this?

I made sure to include the missing brace at the end of \end{document . But it still giving me the same error. It says

I have been trying to insert a PDF document without any success. I have used both TeXmaker and WinEdt. When I am using a PDF file, I make sure to compile using PDFLaTeX, and I have even tried to use an EPS file and I compiled with LaTeX. It still doesn't work. Each time, it gives me the same error ...
