Check If Field Is Empty

I'm listing records from my db and each company has 3 address lines ie address, address2, address3. In most cases 3 and sometimes 2 are empty. As my ASP looks like this

[VBS]
<p><strong>Address/strong> <%= rs("Address") %><br>
<%= rs("Address2") %><br>
<%= rs("Address3") %><br>
<strong>Town/strong> <%= rs("Town") %><br>
<strong>Post Code/strong><%= rs("PostCode") %><br>
<strong>Telephone/strong> <%= rs("Telephone") %>
[/VBS]

then I end up with the first line of the address and two blank lines. How could I avoid that by checking if the fields have content, only then display them?
