You create an Excel list. Each booky has an excel sheet. Each new Dollar in gets a Serialnumber based date received mmddyy and hit position. On each transfer the recipient booky adds date received and hit position.
That is done in a sheet that shows
Canteen 10 Dollars
666 meat
999 fries
...010125666
...010125666
...
The sheet calculates in a hidden field that the amount field (10) and amount of mmddyyhitpos match.
The hit pos meat has
7n7 Paddies
8n8 Meatballs
and additional to the 010125666 colum locked for his access another Colin he enters
0201257n7
The sheet has one more locked for all except the super booky sheriff colum in which the two are combined to be transfers further.
The sbs has a sheet that runs checks throughout all sheets.
