i am able to save mutiple records at once but all the records are the same even if i selected/typed different values in each row. it is only saving the values from last row but the dates on the Leave_Date__c are working fine.

for example this is what i typed:

                Id                               Date           Remarks          Days Off

a3He00000000ktX            09-05-13              A                    Whole

a3He00000000ktX            09-06-13              B                    Half

a3He00000000ktX            09-07-13              C                    Quarter

these are the records saved:

                Id                               Date           Remarks          Days Off

a3He00000000ktX            09-05-13              C                    Quarter

a3He00000000ktX            09-06-13              C                    Quarter

a3He00000000ktX            09-07-13              C                    Quarter

codes:
