Insert multiple records into a table

I have a list of items I need to include for each record on a table.

I have table : Forms  (this has a list of forms in our system)
I have table : x_refernece  (this has the ID of the form "Qid" and a field for 'usertype'

There are many usertypes such as beneficiary, contact, father, mother, etc.

In the x_reference table I need to insert one row for every usertype for every form I have. So I would end up with something like:

Qid: 1  |  usertype  'beneficiary'
Qid: 1  | usertype 'mother'
Qid 1 | usertype 'father'  

and so on. all usertypes, then the query needs to go to the next form, take the Qid and insert into the x_reference table

2 | beneficiary
2 | mother
2 | father

and so on, I should end up with 10 records or so (one for each usertype)  for every form (qid) I have.

how can I create such a query ?  
This are the tables involved:

table:  forms
field : qid

table :usermap
field: usertype  (there are many entries there for each usertype, so in order to prevent duplicates the query below will group them)

table : x_reference
field: autoid (autoid)  (int)
field: qid:  (Comes from the forms table)  (int)
usertype:  comes from the 'usermap' table.  (varchar 20)

I can list them by using this query:

SELECT usertype FROM dbo.UserMap
GROUP BY UserType

Select allOpen in new window

I get 29 results. (29 usertypes)
I have 642 forms

This means I should end up with 18618 records if my calculations are correct. each form form with 29 usertypes included.
