Hi,

I'm using a sheet that has Octal values in it, so only 0 tru 7 are used as
numbers.

A value in column F in entered in Octals e.g. 00200, another value is
entered in column G e.g. 00377.
Now I would like the total amount of numbers to show up in Column H, so in
this case 128.

There are a couple of snacks, the following numbers cannot be used and
therefore should not be counted in the total amount; 77 and 176 and 177 and
77777 (77777 is also the last number in the sequence.

Can anybode help?

Paul.
