Forms/Word 2007/Display Entire Field Length?

Have created some basic online forms. Now I am tasked with displaying each entire field length (visually somehow) so the user can see approximately how much room they have to enter test. Examples:Name: Field length highlighted or shaded Location: Underlining would work to indicate field lengthPhone: ( Parenthesis might work )If I type "Enter Name Here" in Properties, under Default Text, only "Enter Name Here" is shaded. The shading does not extend to the maximum length I selected. The field extends that far, but no indicator of the entire field length
