Hide & Unhide cells depending on drop down

Hi
I have a Risk Assessment sheet within my RAMS workbook.
This has now to include a checklist of the risks that are present for the current job. Our H&S consultant company wants the sheet to be blank (i.e. no risks showing, just the first detail page and the last signing page) and then as each risk is ticked on the checklist the risks will appear on the next pages.
I previously had a series of combo tick boxes at the top of the page which hid the risk and inserted blank rows in its place, this worked ok'ish.

I have created the list on the first page with each risk having a drop down (hidden in col AC) box in the cell next it with the wingdings tick.
There is a second sheet which will be hidden with all the risks on in the correct order that they appear in the list.
I want this to copy and paste / insert each risk into the RA sheet starting at cell A42 and keep them neat.
This needs to work and keep them neatly underneath each other depending on what risks are put in (i.e. not just sequentially).

What is the best code to do this?
