Thank you Ray, I have update the db field from VARCHAR to DECIMAL (5,2) and store now the decimal numbers but not with comma use always the dot why?? Then if I use a digital file [downloadable file photo in my case] and select the image product and choose the file on server the Update button seems not work (for try i have inserted the image flower), in the Product Results list the product is visible but not available for download if purchase it, another suggestion for this case???
