The problem was the invalid octal number.
It was reading the 08 incorrectly and producing an erro when trying to increase or decrease this number.
The error is fixed by adding the following to line 58 of user-tracking/www/loading2.tcl
scan $lastday %d lastday
scan $todayday %d todayday
This removes the leading 0.
I can submit this if someone lets me know what to do?
cheers
Matthew
