I have a field that is a dropdown with different interest rates.  I need the result of the entry to populate into another field so I can do further calculations base.  How do you do this?

      Hi,

       

      You need to add a custom calculation javascript.

       

      For example, in the field that you need to pull a listed item from a dropdown menu field use something like this:

       

       

       

       

      var dropdown = this.getField("dropdown field name here").valueAsString;

if (dropdown !="") event.value = dropdown;
else if(dropdown =="") event.value="";

        Ok, I add the script but now when I'm still having an issue with the periodic rate.  So, I have my form, that has one list box updated with the script in your example.  They choose the rate and that rate writes to the Periodic Rates form fields.  Then those fields, have a simple calculation of Purchase_APR/365, etc.  However, the last field for the Cash Advance Periodic rate is not calcualting when the Cash Advance APR changes.  It's holding the last rate and then if you click in the field while editing, it will update the field.  The other two are working fine, it's just this last field.  Thanks.

        Check the calculation order of your fields.

         

        Are you able to share the form with us or post a screenshot?
