new instance problem

hello,

I have a ES4 form that I am working. I have added a row above a hidden table. This row has a button to open "show" a hidden table.

When clicked the table expands. the table has many cells. One cell has buttons to add new instance or hide the table itself. The add new instance upon click is not functioning. This is what breaks.

The hide table works fine.

If I try the same thing but with a table that is not originally hidden then it works fine. New instances occur. I need to reduce clutter on my form so it would benefit me to have it initially be hidden but then the add new instance has to work.

I use the action builder to add the javascript.

any advice?

thanks,
