Hide Field Name

You can leave the field label blank and specify an admin label in the advanced section of the field OR hide it by adding a CSS Class Name and set the title display to none in your themes css.

For all fields you can try adding the following to your css

.gform_wrapper .top_label .gfield_label {
display: none !important;
}

From what I understand specifying an admin label will override the default form field label. So your visitors see one label and you see another. You can then specify your notification email to display the admin labels by using merge tags.

OK So i duplicated what you want.

First. I would recommend you name all your fields something meaningful

Name of point of Contact
Name of point of Contact #2
Name of point of Contact #3

Click advanced in the form field and enter a css class name (example 'nameblank'). This should only be entered for the fields that you want to hide the label for ie #2 & #3

paste the following in your themes stylesheet:

.nameblank .gfield_label {
display: none !important;
}

.nameblank {
padding-left: 178px !important;
}

Save the stylesheet. The changes should now be made. The first css code block hides the labels. The second block sets the padding. You can change the padding value to suite your needs.
using this method you dont have to enter a admin label.

Apologies for my bad coding in advance.
