    Order payment total, moved to calc field, is not updated correctly

    Asked by bdoodle on August 01, 2015 at 08:07 AM

    I have a calc field, "original total" #id_295, which I populate by inserting the order payment total unconditionally.  It is reliably updated any time the order payment total changes as the result of an update to the order of products having options (e.g. visors and hats). However, when the order payment total changes as the result of an update to any of the last three products on my order form, the "original total" amount is no longer the same as the order payment total.  

    See example below:


    The simple calc field update is shown below:


    Please advise.

    I can see that your calculation is "lagging" one step after the updated payment options. So when the price is updated in the payment tool by selecting another product, that price is not automatically re-calculated by the Form Calculation.

    I have tested by adding another field to the form, and forwarding the payment tool total to it by using Conditional Logic, and it seems to work fine and is updated instantly.

    I would advise you to please try using a regular form field and forward the payment total to it conditionally, rather than calculating it in a Form Calculation field.

    Please let us know if you need further assistance.
