tables? best use of

Hi

Im new to this so forgive my terminology please.

I am trying to develop a document to maintain records of a group Im running,
In order to receive the same information from all the staff I have been using
fill in forms. However as group numbers change each day I was wondering if
there was a way to have an option to select the number of participants which
would in turn create a lsit for completion for that respective number.

Ie a design similiar this

Q. Number of Participants "select "

participant 1
Name "details"
age "details"
Address "details"
Took part "details"
Q
Q
Q

Etc
And the only editable part being the Details and select areas.

Any assistance on how to do this would be great, or am I trying the
complicated / imposible

thanks
