Disable list box in access?

In access, I have a very list proverbial box with a listing of entries as well as a tick container.I need to make it to ensure when that tick package = accurate, the listbox can be utilized, but while =false, it is not used.Having looked throughout the properties, I cannot discover anything resembling a new direction – and for this reason, neither in VBA.

listbox1.enabled=true

listbox1.enabled=false.
