Thanks Massa, I will try to study

  1. However,I found a bug in the built in setting. When I click on the particular row of a table ( the first selection), the repeater of the second collection change correspondingly as expected. This only works for a new row.
  2. When I clicked on the previous row of my first table, the repeate of my collection cannot show the change. Any suggestion?
    Thanks
