We wrote a custom add-on for Act!, using the SDK. Now the customer has three price fields on Product level (default price, and 2 extra custom Currency fields).
Now, since we cannot import non-standard fields while importing products, they us want to write an import function that imports products, and automatically fill also those price fields.
But how do I set a custom product field's value?
I've tried this but it does not work: (see attachment)
