Pre-populate PayPal wizard with number of recurring payments.

I need to send custom URLs to customers which will take them to a pre-populated form that they can then use to make payment to use using PayPal.

Within the PayPal wizard there is the option for the user to select the number of recurring payments.  I am able to pre-populate the amount of the each recurring payment, but what do I need to include in the URL to the form that will select, say, 3 as the number of recurring payments?

If this can't be done directly with the URL, is there a workaround using a hidden text field which can be pre-populated with the required value?

(The URL of the web page that I have entered below includes information to pre-populate some fields.)

Thank you.

I'm sorry, but I don't think prepopulating the payment property is possible. The dropdown option doesn't have a name selector which is used for this method. In fact, our prepopulate app does not support the custom amount box, http://prepopulate.jotform.io/ so it needs to be a variable type which can be used to assign a value via a textbox field/calculation.

A workaround is maybe, by using the source codes embed and by adding a custom script or name selector for prepopulation. I'll try it and let you know.
