userform combobox fills from selection on sheet

Hello all,

I am stuck trying to fill comboboxs on a user form from what a person selects on the sheet.

In attached if person picks 5 fruits from the list each combobox will load the 5 choices.
The fruits are listed in column B while the person will put an X in column C.
The fruits in B with the X in column C will load in combo box.

This sounds easy but not for me.

Please take a look at attached.
Any help is appreciated.
