Cannot create query that needs parameter

[rhayhurst]

Hi.  I'm a total noob and not a Java developer.  I'm also totally desparate.

I want create a table with parameters.  This means that I the SQL must contain parameters.

In order to add parameters, the dataset needs to exist. 
In order to create the dataset, the parameters need to exist. 

Paradox.

Specifically, here are my steps.  
- I've created a report using a template that I created.
- Next, I need to create a table.  I drag the element into the "Details" band.
- The Wizard starts, which will create a new Dataset.
- I name the Dataset, and tell it to use the existing connection.
- I give the SQL, which contains syntax for parameters.  ("...WHERE logs.AccountID=$P{accountId}...)
- I get an error:  Exception... Reason: Parameter "accountId" does not exist

Of course it doesn't exist!  I haven't had the chance to create it!

Can anyone help?
