Use Search Qry Result For Something Else

hi :D
here is my question:

i have a table (tblmembers) with member data (name, last name) etc.
i found how to run a search qry with parameters to ask for name, last name.

i have another table (tblrelationships) with 3 fields
2 for member id's and 1 for the type of relationship they have

i need to run the search query for the member by name (from tblmembers) and use his member id (from the member table) to add it to a new record in the relationship table (tblrelationships).

when i run the search qry, i only get as the result the fields with the member information..
thanks
