amount of chemicals being made and financial rapport 2008

i left the financial rapport for 2008 on the table.
i made a xl sheet with use of chemicals sum up until 1 of april 2009.
in order to be able to calculate the costs i have to know, how much litters of chemicals were prepared between 01-01-2009 and 01-04-2009 ? can some one write it to me?
after sending the xls sheet with costs of chemical use (until end of 2008), i received another invoice from aap and realized that the cost for a 50 litter set ( 25 liter developer and 25 liter BX) is 62 euro exclusive 19% BTW.
that is why i ask to add the 19% on top of the calculated sum and to pay the following amounts:
maarten € 15,13
ilya € 14,67
eva € 8,06
danielle € 5,10
rebecca € 8,21
maartje € 16,38
jeroen € 4,32
marieken €1,90
nobody paid his/her part until now , please do it a.s.a.p because we are with 150 euro in out bank account.
when you make a new chemicals , than write it down in the log book the amount that was prepared. this is the only way for me to know, how to calculate the costs.

eva, can you write how much chemicals you prepared in 1 of april?
lets cooperate on marieken contract assignment and meet beginning of may....
thanks and have a nice time....
