child form shows fields thought I had hidden

Hello All,

I have defined a master/detail form and I am seeing some columns that I thought I had unchecked the boxes on.
In the actual form itself for the table the fields are not there,which is correct.
But when I go in through the parent record/page and I see the columns laid out in a grid the ones I had unchecked the boxes for are there.
Any idea where I am going wrong?

Thanks.

It depends on which checkboxes you unchecked, if you meant Master/Detail-Add/Edit, the columns in the detail are based on the settings for the List page of the detail table.
