1st time to use infopath, not real savy (Obviously), what is CAML query, what is the advantage? I am currently setting this form up with cascading dropdown boxes (4), and am almost done (had uniqueness filters working, had cascade working, strougling with getting them working at the same time. currently using this expression in the filter for the 1st box (working as it is just a uniqueness filter):
not(. = ../preceding-sibling::dfs:Pipe_Classes/@Pipe_Class)
In the second box I have tried this which does not work for uniqueness + cascade functionality:
not(. = ../preceding-sibling::dfs:Pipe_Classes[@Pipe_Class = current()/Pipe_Class]/@size)
The cascading structure is as follows (all boxes being pulled from the same sharepoint list):
User selects Pipe Class (Drop down 1),
This limits the selection available of "Size" (Drop down 2),
Which limits the selections available in "Component Type" (Dropdown 3),
Which in turn limits the selections available in "Description" (Drop down 4)
I am sure if I can get the second box working, I will also be able to get the 3rd and 4th boxes working as well. Can you see / point out problems with my BLOCKED EXPRESSION?
