Fillable forms

The form field is smaller than the area needed to display the result. You need to make the form field larger or the font size smaller.

Do not use any under score as the field default as they will be treated as a field value because they are the field value. This could also cause you issues in other fields that use the value of this field.

Instead make the border for the field an underscore.

Thank you for that.  Why isn't it a good idea to put underscores in the field?  I'm not sure what static graphic is? 

The plus sign means that there's more text in the field than can be displayed on the screen. Delete some of the underscores and it should disappear.

However, it's not a good idea to add these underscores to the field. If you want to have a line then you should add it as a static graphic, and then add the text field on top of it.
