Is this code right ? Because only fnsku, sku and asin values are not updateing

Is this code right ? Because only fnsku, sku and asin values are not updateing

Here is the code,

lstv = input.FNSKU_SKU_ASIN;
if(lstv != null)
{
lstV = lstv.toList(" ");
info lstV.size();
info lstV;
if(lstV.size() == 3)
{
a = lstV.get(0);
info a;
b = lstV.get(1);
info b;
c = lstV.get(2);
info c;
}
if(lstV.size() == 2)
{
a = lstV.get(0);
info a;
b = lstV.get(1);
info b;
}
if(lstV.size() == 1)
{
a = lstV.get(0);
info a;
}
/////////////
insert1 = insert into Form
[
When_it=zoho.currentdate
Added_User=zoho.loginuser
Copy_of=input.Seller
Status="Pending"
Company=input.Seller.company
Email=input.Seller.email
Name_of_the_Product=input.Product1
SKU=input.FNSKU_SKU_ASIN
Size_H_In_Inches=input.size_h
Size_W_In_Inches=input.size_w
Size_L_In_Inches=input.size_l
Quantity_in_box=input.Quantity_in_a_box
Weight_In_Lbs=input.weight
FNSKU=a
SKU=b
ASIN=c
];
}

Basicallly,   the FNSKU_SKU_ASIN has the concatening value stored.

I have tested using above code as in screenshot in deluge editor and it is working fine.
But when it comes to insert task only this fnsku, sku, asin are not working.
