Hi GTalburt,
In order to assist you better, I have few questions based on your explanation.
1. In the second part you mentioned that "you add a grid to new section and added 2 new fields to that grid". Are you adding fields in the grid or you are adding objects?
If you are adding fields, What kind of fields you are adding and from which table?
I tried to replicate what you explained and I assume that you are trying to say that in the grid the dropdown list is not showing, if that is the case then just see the example
In this case you will se there is a dropdown field Customer:Job on the right side of the screen and when you create your sales order, the sales order goes to GRIDon the left hand side. If you see there is same dropdown field- Customer:Job in the grid but here it is just showing the sales order that is being created for the customer. In the grid you can not see the dropdown list, it will show you the value that is there in the sales order.
Hope this helps. In case of any issues feel free to contact us .
