I'm making up a form with a lot of lines and borders. How come sometimes I can erase a line and other time it just looks faded (which I assume is a gridline?) It is getting very frustrated as I cannot type anything in the places that there are gridlines. How do I get rid of them?? Any help would be much appreciated!

If you have a table then you can only "fade" the border. That means that when you print it, it will not be seen but it is useful to see it in your document so you know where it is and you can work with it.

If you can delete it, that I suppose means that you are not using table, but drawed lines or used autoshapes.

So if you want to have your form easily to be filled with data, use tables.
