Photoshop :: No Action In My Action

i am trying to build an action where the end product is a channel listing that has all the channel (R-G-B-L-C-Y-M-K (forget LAB a-b)). this will allow me to look at all the channels for contrast and subsequent extraction. i'm actually able to do this as i RECORD the action. but when i RUN the action, nothing happens.

in recording the action, i create a DUPLICATE IMAGE, then convert the new image to LAB. i then drag the "L" channel to the original image. it goes into the original image as an alpha channel which i rename to "Lightness." i then convert the duplicate image to CMYK and then one-by-one DRAG the individual channels to the original image. at the end of this process, i have all eight channels visible in the channels palette. this is what i want.

but then, when i RUN the action on a new image, the action fails to RECORD the "drag step and drop" step. the "L," "C," etc. channels are not dragged during the running of the action.

why does the "drag" step not record in the action
