Auto Fill From Selection Of Combo Box

I set up an Access database to track visiting families. Each person in a family is inserted as a seperate row in my table. The table has the following columns: Visitor # (which is an auto #), Head of household, last name, first name, phone, email, address and etc.

The first person I enter when a family visits is the head of the household. I set up a quiery with a pull down combo box in my form so when I enter a new entry I can select a head of the houshold to assign each person to. Since I put the head of the household in first. I can then select that head of the household (this way I can track each family member seperate but still know they belong to the same family). So if we have a family visit that has a husband, wife and a child. There are three entries each having a head of the household as the same. When I use the query to select the head of the household in the combo box I would like the information that is the same as the original "head of the household" entry (address and phone #) to be automacially filled in from the husband's initial entry.

How can I do this? I read some other post with some VB in them like "Me.TextBox = ComboBox1.Column(3)" but I don't understand the syntax too well since I'm new at this.

Any help would be appreciated.

Thanks
