Power Browse Search Form Query

Hello All,

I have a requirement where I plan to use power Browse form.  I have created simple Power forms earlier but this one is taking some thinking.  Here is how the application should work

Application =>We need an inquiry on Items.  User will enter description of any item and Find.  This should  list all items matching that description on the Grid.  This is similar to Item Word Search (P41829).  Now I want to add another grid which shows additional Item and Branch Details for those items which is shown in the first parent grid.  Earlier power form I did, User entered Customer number on form and related details were shown on two grids from different tables.  Here I don't have the key on Form Header, but need to take it from Grid Records.  When
