MySQL ROLLUP: Wrong total for one column calculated by a formula -


in query below, 1 of rollup sums has formula referring other columns. seems in case mysql uses formula in rollup line instead of totaling column values.

the value nertek seems calculated using fields in total line, i.e. (462.053-479.710+0)*2700 , result -47673.9 instead of summing column values 61632-75232-12214-21744-3945+4079-43697+13500 = -77621.

what doing wrong?
