    You pass it like a normal variable ie

    void PrintTicket (TypeData sTicket)
    {
    }

    Ooooh just tried that im still getting errors. Ill paste in my prototype, definition and function call and see if you can spot something.

    Prototype:

    void PrintaTicket(struct TypeData sTicket);

    Function Call:

    PrintaTicket(TypeData sTicket);

    Definition:

    void PrintaTicket(struct TypeData sTicket)
    {
    int iReference;
    int iCustomer;

    cout<<"Please type in your reference number";
    cin>>iReference;
    clrscr();
    cout<<sTicket.sNameArray[iReference]<<endl;
    cout<<"Destination - "<<sTicket.sDestination[iReference]<<endl;
    cout<<sTicket.sNumber[iReference]<<" "<<sTicket.sStreetName[iReference]<<endl;
    cout<<sTicket.sCity[iReference]<<endl;
    cout<<sTicket.sRegion[iReference]<<endl;
    cout<<"Please enter your customer number";
    cin>>>iCustomer;
    }



    i get these errors

    Error: PROJECTb.CPP(211,22):Improper use of typedef 'TypeData'
    Error: PROJECTb.CPP(211,30):Function call missing )

    Prototype should be:

    void PrintaTicket(TypeData);

    Function Call should be:

    PrintaTicket(sTicket);

    and Function Definition should be:

    void PrintaTicket(TypeData sTicket)
    {
    //your stuff here
    }


    cheers

    I cannot thank you enough, and by code tags do you mean commentated code?

    Thanks again......
    .....and again.

    [ code ] [ /code ] (with no spaces) when you post

    ie

    Code:
    //This is a code fragment
    if (toupper(key)=='K')
      cout <<"Going to continue";
    else
      cout <<"Not going to continue";
    //notice how the spaces are kept
    cheers
