How to output user input (string) to the screen inside a procedure with structure passed by reference in asm?

Question

I'm creating a Payroll program using assembly language. I have a structure to hold first and last name using BYTE sized arrays. Also DWORD types for ID numbers and hourly wage. I then created a procedure to collect user input using the structure passing by reference. I posted the first name input for getEmployeeData PROC.

I've tried storing the first name with a local variable (outside of the struct) under .data which gave me random character output.

Employee STRUCT
   first BYTE 16 DUP(0) ; member variables
   last BYTE 16 DUP (0)

   IDnum DWORD ?
   hourly DWORD ?

Employee ENDS

getEmployeeData PROTO,
    emp: PTR Employee

.data   
em Employee <>

.code
main PROC   
    
    INVOKE getEmployeeData, ADDR em
main ENDP 

getEmployeeData PROC USES edx,
    emp : PTR Employee

    mov edx, OFFSET pFirst
    call writeLine
    mov edx, emp
    call readString
 ret
getEmployeeData ENDP

END main

I want to print the name to the screen. Please advise.
