Surfaces subtraction

Hello guys,
can someone please tell me what is wrong with my code?
im trying to subtract the circles from the wall, but it keeps either subtracting the wall instead or joining them.
can someone please help? i tried to hide the nodes one by one with no success.

@nassouh.mahfouz Please post your dyn

Also, try joining the solids extruded by the circles into a single solid - you’re not set to do a recursive subtraction on the wall face, and with either longest or shortest or cross product lacing you’ll still only have many surfaces with a single hole in them not one surface with many holes in it.
