because "@clientid = clientid, @currencyid = currencyid" in the select in assinging values to those variables and "amount" is trying to retrieve the amount value.  You can not do both in one statement.

Does the following work?
Declare @clientid int
Declare @currencyid int
Declare @amount decimal (18,2)
select @clientid = clientid, @currencyid = currencyid, @amount = amount from transactions where id = @id

Open in new window
