Hello everyone. I am new to this websiite. My despair led me to this website.
Here is my problem:
I have this file that composed of four worksheets. Each sheets have a chart(each are in equal cell sizes: 10 cells X 10 cells for example) which are composed of makros(locked). I want to add these chart one under the other with and exact positioning so i can print these chart in A4 paper sizes.

What i need is how to add these chart one under the other with combobox. I really rally need your help guys.

one under the other with combobox.

with box? what? not following.

a box under EACH chart? and each chart below the previous one on one sheet? if so, why don't you just manually move them?
