hey i got this one..
in 2003 ryt...quite simple...
jus right click on the "query design view"
look for "totals"...click it n another row of totals will appear just below the "tables" row
once this is done the row automatically takes "group by"
let the staff remail grouped "group by"
now add two of the income and select "sum" or "count"
ur things done... if u wer able to do it in 2007 u'll surely get it in 2003
i feel 2007 if far better than 2003 for igcse
