thank you very much. thats exactly what i was after. bit cheeky, but how would i relate 2 combo boxes eg
if for example a bottle of beer comes in 2 sizes 250ml & 330ml and a draught beer comes in 2 sizes 0.5 pint & 1 pint, how would you go about making sure that if the first box combo box had bottle selected in it, the 2nd combo box would only show 250 & 330ml and not 0.5 &1 pint?
your help is greatly appreciated.
thank you
