Child table and parent table hooking problem

I have created a custom doctype and also created a child table for that doctype.But after making doctype and connecting child table with the doctype child table is not working correctly.

Note: I did it before and it worked fine. Here is a screenshot to understand the problem.

what is issue??

if i pressed add row and insert data , it does not take data in the log table .

see the list is blank

you should set yes for list_view of any fields.

how do i set it brother. I think i forgot the process.can u help me out? or maybe i didnot need to set it before. quite confusing though :confused:

just go to your child doctype and set property (list_view or grid_view) checked for fields which you want to show in list view of child table.

Thanks man . Problem solved.
