Adding rows to the DataTable

[newqtp]

Code:

p=datatable.AddSheet ("My").AddParameter("city","New York")

i=datatable.GetSheet ("My").getcurrentrow
msgbox i 'This will give 1 as the current row is 1.

q=datatable.GetSheet ("My").SetNextRow 'This one is getting null value.It should show 2
'but nothing
msgbox q

datatable.getsheet("My").Setcurrentrow(2) 'then i've used this cuz i know my current
'row index is 2
'******** Both code below worked for adding value in run time data sheet.
'datatable.Value("city",3)="Bombay"   '3 is for sheet index  for Sheet name My
Datatable.Getsheet("My").GetParameter("city").Value="Bombay"

Data=datatable("city",3)'getting  current row value from sheet My index 3
msgbox Data
