Pass information from popup subform back to main form

Pass information from popup subform back to main form

I am developing a form that has multiple subforms on it.  The subforms work great on a normal computer however the Zoho Creator mobile interface has a defect as it cuts off the subform fields, doesn't resize when I turn my phone and to scroll over you have to swipe sideways on the sub form itself.  This form is also public facing so it makes it difficult to train everyone on how to use it in a way that makes it work.  To get around these problems I have been instead trying to use the openurl command to open up the subform as a popup window when I click on the Add New link of the subform.  I am able to get the subform to open as a pop up and able to submit records however when that window is closed the data I have submitted doesn't show on the main form.  Does anyone know if there a way to have the new records just added to display on the main form?
