Using named fields and ranges in macros

I've created a few simple macros to help me maintain a simple user list.
I would like to use names to define columns, rows, cells and ranges and use them in my macros. For example, part of a macro might use:

Columns("D:P").Select
Selection.EntireColumn.Hidden = True

I can give a name to column D and to Column P but I can't figure out how to use it correctly in the macro. I imagine that I'd use something like:

Columns(phoneNumber:addressLine3).Select

but this gives an error.

It's likely something very simple that I need to do but I can't find the trick via the help information.

Can you help, Please

Thanks

you have to use quotations for the colon

Columns(phoneNumber & ":" & addressLine3).Select

Keyur

And it seemed so simple....

I gave Row 5 the name: "PaymentTitle"

When I use
Rows("5:5").Select
Selection.EntireRow.Hidden = True

it works fine

but when I use
Rows(paymentTitle & ":" & paymentTitle).Select
Selection.EntireRow.Hidden = True

I get "Type Mismatch" error 13

Obviously an simple row NUMBER and a row NAME are not interchangable.
