Without seeing some source code, there's not a lot we can do except admire your artwork.

It's hard to help you with your code if you don't show the code!

Are both these displays generated by the same function? Are you sure you're passing a name to the function in the first instance?

Have you tried stepping through the program with a debugger to see why a name isn't passed/displayed?

here is my code

int main()
{

// open file

openFile();





// if file fails to open
if (inFile.is_open())
  {   


      PrintHeader();
    while (! inFile.eof() )
    {
    process();
   }
    finishUp();
inFile.close();
  }
  else cout << "Unable to open file"; 

  return 0;
}
/* Open File */
void openFile(void)
{
    inFile.open("HBdance.fil");
    return;
}
void process(void)
{
    file();
    performCalc();
    PageBreak();
    displayReport();
    getline(inFile, line);
    tRec++;


return;
}
/* Calculations */
void file(void)
{
    inFile >>sFname>>sLname>>fcloth>>ftrans>>fFlowers>>fdinner>>ftickets>>magQty>>canQty;
        strcpy_s(sStName,sFname);
        strcat_s(sStName," ");
        strcat_s(sStName,sLname);
return;
}
void performCalc(void)
{

    cDrive();
    mDrive();
    Calc();

return;
}


/* Display Reports */
void displayReport(void)
{





iLineCount = iLineCount + 2; 


    grandTotCost = grandTotCost + totCost;
    schTotCost = schTotCost + scCost;
    parTotCost = parTotCost + pCost;
    stuTotCost = stuTotCost + stCost;

    cout<<fixed<<setprecision(2)<<endl;

return;
}
void PageBreak(void)
{


    if (iLineCount >= 12)
    {
 system("pause");
  PrintHeader();

    }


    return;

}

void PrintHeader(void)
{




   iLineCount = 0;   //reset line counter to 0

   system("cls");
    cout<<"\n                          High School Dance                               ";
    cout<<"\nCurrent Name: "<<sStName;
    cout<<"\n\n     Name           "<<"Parents Cost   "<<"Student Cost   "<<"School Cost   "<<"Total Cost   "<<endl;




return;
}
void finishUp(void)
{

    gTotals();
    tRecords();


    return;
}

You call PrintHeader() before calling process(), so sStName is empty on first call of PrintHeader()

...and please use code tags!!!

It also is apparent you are using a LOT of global variables. This is generally a poor practice. Had you been using local variables (most of which would be declared in main() ) you would have been able to see your problem sooner.

Go back to your text and notes on constructing functions - use the parameter list to limit what data a function can see and affect.
