Please Help A Newbie

Hi

Can anyone please help?

I've been doing the Loadrunner tutorial & i'm struggling with what syntax to use adding a 'char' I've created & adding it back in the web_submit_form ITEMDATA

Below is a short example of the code im having trouble with;

char * FlightVal;

web_reg_save_param("outFlightVal", 
        "LB=outboundFlight\" value=\"", "RB=>", 
           "ORD=ALL",
        "SaveLen=18",
        LAST );

FlightVal = lr_paramarr_random("outFlightVal");
 
lr_output_message("Flight Value is %s", FlightVal);

web_submit_form("reservations.pl_2",
        "Snapshot=t5.inf",
        ITEMDATA,
        "Name=outboundFlight", "Value={?}", ENDITEM,
        "Name=reserveFlights.x", "Value=44", ENDITEM,
        "Name=reserveFlights.y", "Value=9", ENDITEM,
        LAST);

If anyone can help me with what I add in "Value={?}",   in order to display the value of  FlightVal would be very much appreciated.

Sorry if this is very newbie im just trying my best to learn.
