Is there a way to adjust properties setting on a text box so that it will display more information?

This is a one to many relationship.

So for instances... On the report i have one customer (TOM) owning 2 CARS.
On the TagNo. or Reg.No text box it will only show up the first CAR, but no info on the second CAR. Is there a way to excecute it without doing subforms?

it will only show up the first CAR, but no info on the second CAR.
That is the point of the subform to show the "Many". The main form shows the "one", and the subform shows the many [cars] in your case.

im glad that clear things up!! thx

My answer was very simplistic but, I am glad you got the message.
