Hi,
Catch the item event of After Item Pressed of the 'Next Button'
Check the pane level of the current form, if it is on step 6 (pane level = 5), draw your button.
or
Catch the formload event of this formtype '504', Draw the button and set this item.frompane and item.topane = 5
If you need more information on catching item event and pane levels, check the SDK samples in your local folder.
