Wording regarding property left in a will

Hi all, can anyone please tell me what happens if a few family members are left a property that is sold before the death of the will writer?
In this case 6 people are left the property and the rest of the estate is split equally between them plus 4 others (10 People).
If the property has already been sold - does the money now get split equalyy between the 10 people?
"any house that I should occupy at the time of my death as my principle residence in shares as set out below, subject to any changes made on the property having either been paid for from my estate or the sale of the said property"
Thanks for any help
