Data fields selected in a form are not displaying

Question

I have selected "Size" & "Outlook Data File" as 2 fields that I need to see on the front tab of all my contacts.  In testing to see if it works I opened a new contact (blank).  Upon it trying to open I get the same error
twice  "The Property does not exist.  The field you want to modify does not exist for this type of item."  I don't want to modify these two fields, just display them.  I chose the same field names in the forms developer/design
area as when I added the field as a display cols. in a simple list of contacts (e.g. phone book).  So it works in Viewing a list but I can't see these 2 fields when I add them to a form.  More precisely the labels show, "0" shows as the
size and blank in the other display field.

Hi Steve,
Situation:  Through the yrs I've had multiple email domains.   I've discovered that as I opened and edited contacts they did not always save to my main contact  (.pst) I want to consolidate my contacts to my new one.  
If I open the same email address from 3-5 different .pst & now MSX too, I want to know which file (domain) they are being displayed from so I don't necessarily have to ck every field to know if I can simply delete one or if I have to go field
by field to do a merge.  Secondly, I've found that some contacts from older domains never got to my current .MSX so I'm trying to figure the best way to see these.   (Doing an export, then import & then removing dups is not a feasible answer. 
The exports truncate my notes to 250 chars so I loose too much of my history.)  I added "InFolder" to the contacts form but several say "contacts" so that is not enough to differentiate them.  I tried to go & change the name of the older contacts
folders but still have 3 contacts folders that I can't seem to change.
"A field appears in the Field Chooser but it doesn't mean we can use it on every type of Outlook item. We can only use fields appropriate for the form we are designing."  I realize this but these 2 fields are available & display beautifully when
I select them in my "View" of a list of contacts so it's associated in the OutL database.  Seems logical that it should be on a design form too.
Is there another suggestion for differentiating where the source of the contact comes from?
Not sure I follow what you mean by, "We can also post in Outlook for Developers forum to check the properties of Outlook contact form, and confirm which fields we can add to it:" ?? Will this serve as that posting or are you saying post a separate thread?
