How i can allow null value getting from orchestrator

i read data from excel file which contains different data like day date description fuel etc.
i store this data in a dataTable . and then add to queue using bulk queue items activity .
Now i retrieved data from queue using get transaction item.specificContent. i have null value like thisfuel .
the data is fetch where value have. but showing error where value is not present.
my question is that how can i allow empty field .fuel1


Instead of directly accessing values from the transactionitem, try to convert it by using Convert.Tostring("yourValue) then use it, this will avoid the “object reference not set to an instance of object” error. so try like that.

TransactionItem.SpecificContent(“xxx”) is Nothing

is the solution.
