Q - Can I use this plugin to place more than one iframe in a page or post?
A - Yes. As many iframes can be embedded in a page or post as you may want. Just increment the field name, say from iframe1 to iframe2, iframe3 ... iframeX. For example if you wanted three iframes in the page your short codes could be [field name=iframe1] [field name=iframe2] [field name=iframe3] and then in the Name section of the Custom Fields area you would have one for each short code. So one line would have Name = iframe1 Value = < your iframe code > and so on as needed.
