Error when checking if column exists before running query.

I am getting this error when the below query is run "Invalid column
name 'CellPhone'"
if exists (select * from information_schema.columns where table_name
='Customers' AND COLUMN_NAME = 'CellPhone')
UPDATE Customers SET PhoneNumber = CellPhone
GO
The Customers table exists but the column CellPhone doesn't.
SQL seems to try to validate the update query even if its not going to
be run.
If I change the table to something that doesn't exist, it will skip
over the line without any errors.
eg. UPDATE CustomersXXX SET PhoneNumber = CellPhone
So if the table does exist it must try to validate the columns against
the table.
Any ideas on how to get around this? I don't want it to run the query
if the column doesn't exist.
ThanksThere might be better ways but this splits the statement into two compiles:
if exists (select * from information_schema.columns where table_name
='Customers' AND COLUMN_NAME = 'CellPhone')
EXEC ('UPDATE Customers SET PhoneNumber = CellPhone')
