If [ YourTablle::field = "A" ]
Go to Layout ["Layout appropriate when values is A Here" (Table) ]
Go to Layout ["different layout here" (table) ]
There are a number of possible variations. If the value in the field is an exact match to the name or number of a layout, a single Go to Layout step might be used with either the "layout name by calculation" or the "layout number by calculation" options that you can select with go to layout.
The calculation in the If step may need to be different--especially if the field is a check box group.
And you can include Else If  steps to check for more values that control what layout should be specified.
That is exactly what I needed. All works as i wished.
