[sudhirzpatil]

Hi I have Put Text output value to get run time Text displayed for different iteration. I am able to get expected text output for first Data.
But for rest I am getting blank value.
Please find the below code.

Code:

Browser("Welcome: Mercury Tours").Page("Welcome: Mercury Tours").WebEdit("userName").Set "mercury"
Browser("Welcome: Mercury Tours").Page("Welcome: Mercury Tours").WebEdit("password").SetSecure "4d2496e99823041ab2967b1e5a53f5b8b003ec3c"
Browser("Welcome: Mercury Tours").Page("Welcome: Mercury Tours").Image("Sign-In").Click 20,10
Browser("Welcome: Mercury Tours").Page("Find a Flight: Mercury").WebList("fromPort").Select "Frankfurt"
Browser("Welcome: Mercury Tours").Page("Find a Flight: Mercury").WebList("toPort").Select "London"
Browser("Welcome: Mercury Tours").Page("Find a Flight: Mercury").WebList("fromDay").Select "6"
Browser("Welcome: Mercury Tours").Page("Find a Flight: Mercury").WebList("toDay").Select "11"
For i=1 to Datatable.GetRowCount
Datatable.SetCurrentRow(i)
Browser("Welcome: Mercury Tours").Page("Find a Flight: Mercury").WebRadioGroup("servClass").Select DataTable("Class", dtGlobalSheet)
Browser("Welcome: Mercury Tours").Page("Find a Flight: Mercury").Image("findFlights").Click 33,6
Browser("Welcome: Mercury Tours").Page("Select a Flight: Mercury").Image("reserveFlights").Click 24,13
Browser("Welcome: Mercury Tours").Page("Book a Flight: Mercury").Output CheckPoint("Book a Flight: Mercury Tours")
Browser("Welcome: Mercury Tours").Page("Book a Flight: Mercury").Image("buyFlights").Click 47,15
msgbox Datatable.Value("Book_a_Flight_MercuryOutput_Text_out", dtglobalsheet)
Browser("Welcome: Mercury Tours").Page("Flight Confirmation: Mercury").Image("backtoflights").Click
