hey i am just learning maya because i have a course i am using it in. one of the assignments i need to use the lattice deformer to make a cylinder form to the shape of a plane blueprint.

i have created the cylinder and put the lattic around it, but when i go to move the lattice points, only the end points deform the cylinder, the rest doesn't deform it at all. i remember other people in my class had this problem, but i wasn't paying attention, so i was hoping someone could help me with the problem?

the basic steps i take are;
create the cylinder
rotate x 90 degrees
resize it for the body of the plane
i then select the cylinder and create the lattice
then i choose lattice points with only the lattice selected
move the lattice point, and the cylinder doesn't deform.

if needed i will attach screenshots, just hoping that someone could point out what i am doing wrong.

addition; just a note incase it matters, i am using polygons
