Data Element in a for loop with if statement

[EstherV]

Hi Community,

I'm currently using some custom code in a Data Element to return a price range of a specific product.

This code is working, I'm already using it on pages with a single product.

var productPrice= window.tc_vars.product_unitprice_ttc;
var tranche;

switch (true) {
  case (0 <= productPrice && productPrice < 299):
    tranche = "/Less than 299€";
    break;
  case (299 <= productPrice && productPrice < 301):
    tranche = "/Between 299 and 300€";
    break;
}

I would like to use this data element on my basket page where I have multiple products and stock the returned value in an eVar:

s.products = "";

for (var i = 0; i < window.tc_vars.basket_products.length; i++) {
  s.products +=
    /*window.tc_vars.basket_products[i].product_cat2_name +*/ ";" +
    window.tc_vars.basket_products[i].product_id +
    ";"

  if (
    window.tc_vars.basket_products[i].product_unitprice_ttc &&
    window.tc_vars.basket_products[i].product_unitprice_ttc !== ""
  ) {
    s.products +=
      "|eVar34=" + "HOW CAN I USE MY DATA ELEMENT HERE?";
  }
}

My goal is to use the formula stocked in my Data Element for every product in my basket. But I'm not sure how to use my data element here.

I know that this is not working:

s.products += "|eVar34=" + window.tc_vars.basket_products[i]._satellite.getVar('ProductPriceTranche');

I tried the following :

s.products += "|eVar34=" + _satellite.getVar('ProductPriceTranche');

It's returning an empty string.

I can't find how to fill in the product index dinamically in this line of code.

Any suggestions here ?

Thanks !

Your last code sample is how a DE should be referenced

s.products += "|eVar34=" + _satellite.getVar('ProductPriceTranche');

The DE code should return a value

return 'value'

Hi @Andrey_Osadchuk, 

The DE is actually returning a value we forgot to add the last line. But the DE is actually returning the var tranche

return tranche;

So if I'm understanding well your comment, the DE reference is correct so I just need to do some test with some other products ?
