Change the alphanumeric entry data into the same alphanumeric data but with spaces or dash

Good day everybody!

I'm a novice.... in many things ....Please to have some helps from all of you....

1) What should I program or format in EXCEL 2010 for the following alphanumeric text entered by user for instant:

65G00512707

Into the following after the user presses the Enter button on the keyboard:

65G 005 12 707 or 65G-005-12-707.

2) Why is that after several file opening/saving (File created = form), the check boxes (Under Control - Developer Menu) that are put in the created form, are moved to the other unwanted location on the form ?
Please advice.

Regards & many thanks,
Linda,
the novice.

Another method (slightly shorter)...

=LEFT(D4,3)&TEXT(MID(D4,4,8),"-000-00-000")
