Comma, colon or end of line expected

I have error in line 13 called "Comma, colon or end of line expected". I want to write a program that's gonna write ascii heart at the X, Y possitions. As you can see i use pattern

(Y*80+X)*2

 org 100h

MOV AX,0A000H
MOV ES,AX
MOV AX,poz_y
MOV BX,80
MUL BX
ADD AX,poz_x
MOV BX,2
MUL BX
MOV DI,AX
MOV AL,9825
MOV BYTE PTR ES:[DI],AL
poz_x dw 160 
poz_y dw 100

NOW:

Thanks to you all for your response :) Now Im trying to display ASCII character at this point, its compiling but doesnt do anything: 

 org 100h

MOV AX,0b800h
MOV ES,AX
MOV AX,poz_y
MOV BX,80
MUL BX
ADD AX,poz_x
MOV BX,2
MUL BX
MOV DI,AX
MOV [ES:DI], word 2d04h     

mov ax, 0x4c00
int 21h

poz_x dw 160 
poz_y dw 100

The PTR operator is only used in MASM.

NASM doesn't use it, so in order to assemble your code, you will need to remove it:

MOV AX,0A000H
MOV ES,AX
MOV AX,poz_y
MOV BX,80
MUL BX
ADD AX,poz_x
MOV BX,2
MUL BX
MOV DI,AX
MOV AL,9825
MOV BYTE [ES:DI],AL      ; ← change this line
poz_x dw 160 
poz_y dw 100

Note that the BYTE isn't actually needed here—the assembler can tell that you're storing a BYTE-sized value, since the source register is the BYTE-sized AL. However, it doesn't hurt to include it.
