Need Help

Let me say that I am an absolute noobie without programming background. Someone else in the forum has pointed the following steps to install CCK Fieldgroup Tabs:

1) Installed CCK and activated all (include content and fieldgroup)
2) Installed Tabs and activated
3) Installed CCK_fieldgroup_tabs and activated
4) Created a new content type called "tabpage"
5) Created a field called "test1field"
6) Created a fieldgroup called "test1fieldgroup" (remembered to select tabs)
7) Told the field "test1field" that it shoud be a part of the fieldgroup "test1fieldgroup"
8) Created a field called "test1field"
9) Created a fieldgroup called "test1fieldgroup" (remembered to select tabs)
10) Told the field "test1field" that it shoud be a part of the fieldgroup "test1fieldgroup"
11) Gave permissions to view the fields under User > Permissions
12) Went to "display fields" and choosed "tabs" in both Teaser and Full node
13) Created a new page based on my new contenttype "tabpage"
14) When creating there was two tabs as expected

My question is, how to do step #7 and #10? How to link the field to the intended group?
And also, what is the field type for the field? (decimal, integer, float, text, node reference, user reference)?

We're trying to have several Pages grouped together in one set of Tabs.

Thank you for your help.
