Werls, please don't take this the wrong way, but I would really like some help here. I must be missing something. The half year shows revenue of $11+ mill ...great result....but the monthly cashflow result (4c) only shows receipts of $149,000 from customers for the seven months to Jan. I assume they must have made a product sale in the Dec half that hasn't been paid for yet. Is that right? (I note from the 1/2 yly a/c's that the revenue split is $3.9 mill for contract income and $7.4 mill for product sales, the balance being made up from interest and such like)
