Hi
I have a dbgrid that looks as follows:
Size 0.9 1.2 1.5 Cubed
100x50 1 5 2 0.0495
Size is extracted from another table by using an id key and a lookup
combobox that saves the sizeid in the table that makes up each line in grid.
Size table has these fields:
id Size LinealFactor
e.g. 15 100x50 0.005
GridTable has these fields:
id Sizeid 0.9 1.2 1.5
egg 2154 15 1 5 2
How can do extract the lineal factor from the size table and use it to
calculate the cubed?
Cubed=(0.9*1)+(1.2*5)+(1.5*2)*100x50 lineal conversion factor
Cubed=9.9*0.005
Cubed=0.0495 cubic metres
regards
Chris Wallis
