Userform Listbox Conditional on Previous Selection

Hello,

I have to populate a list box using the conditional value selected in a previous listbox. That value selected in the first list box corresponds to its own range of values listed in the excel sheet. What is the code that will populate the second list box with the range corresponding to the value of the first?

Attached is the sheet.

for example, When Cambridge is selected in the first Listbox, I would like another listbox to open with the range below "Cambridge MC" on the combolists tab.

Thanks
