รบกวนช่วยดู javascript ให้ทีครับ ไม่แน่ใจว่าผิดตรงไหน
บรรทัดที่ 10
var weight1 = document.bmrform.weight.value
บรรทัดที่ 16
finalBmr1 = 66.5+(13.75 * weigth1 ) + (5.003 * height1)- (6.755 * age1)
บรรทัดที่ 22
finalBmr1 = 655.1 + ( 9.563 * weigth1 ) + ( 1.850 * height1 ) - ( 4.676 * age1 )
แก้ไขบรรทัดที่ 16,22 จาก weigth1 ไปเป็น weight1
(พิมพ์อักษรตัว ????th1 กับ ????ht1)
