suppose the value of no. of rows is in variable 'rowno'

now im sending this to my server for processing by making text button n attaching that to table.
now on my server i retrieve the value from this text button........


now what is happening is that....
if the user add new row after the first.....then a new text field is created for him.
what i end up doin is that everytime user add new row i append a new text field.......im not able to remove the previous text field.....

Can antone help me with this.......
