[Plugin: Iframe Embedder] relative path

Hi, i’m trying to use this plugin in local server (i use easyphp and wordpress 3.4)

i create a new page and i insert this code:
[iframe /VT/VT_Civ_Samb_4Mar12/vt.html 200px 200px]

i’m some proplem with relative path. The vt.hmtl file is the child of:
main directory of the site –> VT –> VT_Civ_Samb_4Mar12

can some one tell me more about relative path? or where i have to saved the vt.html directory file?
