I need help writing a calculation

  • June 30, 2023

Right now what I have is this, but it isn't working:

     var EXT = this.getField("Warranty").value;
     if (Warranty = Extended) event.value = Number(this.getField("Quantity_Tablets").valueAsString) * 279

 

There are four different varieties of warranties with different prices, and based on clickboxes, I need to get the number multiplied by different values.

 

Please help!

    Use this:

    if (this.getField("Warranty").valueAsString == "Extended")
    event.value = Number(this.getField("Quantity_Tablets").valueAsString) * 279;

    Use "==" in the if.  "=" is the assignment operator. "==" is the comparison operator.

    You write

    if (Warranty = Extended) 

    First, this you make the mistake EVERYONE makes. To test if things are equal, you need two equal signs == not =.

    Second, you are comparing a variable called Warranty with a variable called Extended.

    You must ALREADY have set Warranty and Extended to something. On the other hand if you want to get the value of a field you have to use this.getField. And if you want to compare with a string, it has to be in quotes. So, conceivably you really meant

    if ( this.getField("Warranty") == "Extended" )

    but we don't know your intention. Also you don't mention having a field called "Warranty".

    I've renamed the field to "Warranty Charges" and have changed it in the rule.

     

    This is it's current version:

    var EXT = this.getField("Warranty Charges").value;
    if (this.getField("Warranty Charges") == "Extended") event.value = Number(this.getField("Quantity_Tablets").valueAsString) * 279

     

    It doesn't work either. Quantity_Tablets is the total of items ordered, so that's what I want to multiply by the dollar amount.

    You doesn't use the value of the field "Warranty Charges".

    Where does you set the variables Warranty and Extended?

    There is a set of radial buttons that are named "Warranty Charges" and the four Radio Button Choices are Standard, Extended, Accidental and Ext+Acc. I have renamed the button, and the field is now Warranty Charges, but it doesn't work either way.
