I have a dynamic block with attributes. Need help!

My dynamic block is an Index form that has three attributes that need to be copied down as I "stretch" the block. This index needs to have anywhere between 4 and 64 entries. My knowledge of making dynamic blocks is not extensive, I have been doing it for a while, but nothing too complicated.

I figured that I could get the row of attributes to "array" down with the "stretch" action. That doesn't work.

Anyone have any suggestions for me?

What do the attributes need to contain, the simplest way is to have all 64 entries created in your block and then use visibility states to decide how many to turn on, but it means 64 visibility states - I did say simple, not quick. Can you post an example of how it should look and what it needs to do.
