Script check needed

Hi all,

I would like to have a check on the script for my checklist. It has 16 categories and for each category there are 4 options: 0 , 1 , 2 , 3 (for all the options the value is alike, so 0 =value 0, 1 =value 1, etc.)

at the bottom of each option there's a field: subtotal

 now I've added the following code to those fields: 

event.value=(this.getField("Top_0").value+this.getField("Vest_0").value +this.getField("Broek_0").value +this.getField("Panty_0").value +this.getField("Schoenen_0").value +this.getField("Haar_0").value +this.getField("Makeup_0").value +this.getField("Bril_0").value +this.getField("Oorbellen_0").value +this.getField("Ketting_0").value +this.getField("Sjaal_0").value +this.getField("Armbanden_0").value +this.getField("Ringen_0").value +this.getField("Nagellak_0").value +this.getField("Riem_0").value +this.getField("Tas_0").value)

event.value=(this.getField("Top_1").value+this.getField("Vest_1").value +this.getField("Broek_1").value +this.getField("Panty_1").value +this.getField("Schoenen_1").value +this.getField("Haar_1").value +this.getField("Makeup_1").value +this.getField("Bril_1").value +this.getField("Oorbellen_1").value +this.getField("Ketting_1").value +this.getField("Sjaal_1").value +this.getField("Armbanden_1").value +this.getField("Ringen_1").value +this.getField("Nagellak_1").value +this.getField("Riem_1").value +this.getField("Tas_1").value)

event.value=(this.getField("Top_2").value+this.getField("Vest_2").value +this.getField("Broek_2").value +this.getField("Panty_2").value +this.getField("Schoenen_2").value +this.getField("Haar_2").value +this.getField("Makeup_2").value +this.getField("Bril_2").value +this.getField("Oorbellen_2").value +this.getField("Ketting_2").value +this.getField("Sjaal_2").value +this.getField("Armbanden_2").value +this.getField("Ringen_2").value +this.getField("Nagellak_2").value +this.getField("Riem_2").value +this.getField("Tas_2").value)

event.value=(this.getField("Top_3").value+this.getField("Vest_3").value +this.getField("Broek_3").value +this.getField("Panty_3").value +this.getField("Schoenen_3").value +this.getField("Haar_3").value +this.getField("Makeup_3").value +this.getField("Bril_3").value +this.getField("Oorbellen_3").value +this.getField("Ketting_3").value +this.getField("Sjaal_3").value +this.getField("Armbanden_3").value +this.getField("Ringen_3").value +this.getField("Nagellak_3").value +this.getField("Riem_3").value +this.getField("Tas_3").value)

for the total field I used the (2nd) option: Value is the sum(+)

now when selecting the options, the total field is calculating the values correctly, only in the subtotalfields there's no value visible, so it looks like it isn't calculating. 

Can you help me with this? Is it something in the code?
