Hi there
I have used your method to create a shopping cart function on SharePoint 2013, but the "select size" isn't showing any available choices from the Picture Library I created. Please can you assist with getting this one field to work.
What type of field should I create for the AvailableSize field in the picture library. Is this a simple line of text field, or choice field.
What sort of field should I create in the list that the data is supposed to be pushed to.
