data assist
Thanks for the replies guys.  I hand coded the sql in the end.  I will look at the solution given above.  One of my reasons for buying web assist plugins is to speed up my production and so improve on the profit margins. 
I know this will happen in time.  The learning curve may be a bit steeper than I had thought.  Given the complexity of what some of the plugins are doing this is understandable.  I need to set aside time to learn the wizards etc.  The volume of work makes this a tad hard...
I would however like to see user guides with more depth to them. I find the quick starts are ok but for example, the checkout wizard in ecart does need seem to be very well documented or perhaps I am just not looking in right place.
Thanks again.
Jon
