here the query, " i am tranfering water from one tank to many tanks. but the condition is there are 5 systems are available. each system having some number of tanks. the tanks are maintained by 'Tank Number' which is unique in the whole environment.
initially i wil pick system. using ajax function i wil auto populate tank number which residing at particular selected system. after selecting tank number i wil generate tank parameter to be filled like initial level, final level, total quantity, etc through ajax. the tank parameter are in both source and destination side. but these parameter varies by number. like source tank have 'purity of water', etc which is not present in destination tank.
now the problem arises when transferring water from one tank to many tanks. because at source tank values to be entered only once. and at destination side the person wil fill 1st tank. and based on the situation he will decide to fill next tank.
