Drop down lists to change all data

I have several worksheets that all relate to one one cell C3 (for reference)

I have a dropdown list on my first worksheet to change the value of C3



I would like the same dropdown on a few other worsheets as well.



In effect several dropdowns on different worksheets but all effect and change the value of the single C3 cell.



Any takers ?
