Unable to retreive the input tex box values from previous step of a wizard, in the current step having a table builder

We have a requirement for mass change quantity update, where we have 2 input text boxes in step 1 and in step 2 we have a table builder. The data on the table builder in step 2 would be based on the text box input from step1, but i am not able to get the value of the text box from step1 in the Nmcommand bean of the table builder. Could you please assist me here?
