Iframe opened by OpenURL stopped working

Iframe opened by OpenURL stopped working

Hi,

I invoke an iframe into a HTML snippet in my Page using openURL. I created this workflow a few hours ago, it worked for a time and now is giving me this error: 


I invoke the OpenURL through a custom action. Here is the code:

     My pages are published: 




Also, when I invoke the same report within an iframe, it works. I use the following code:


Please help!

Also, I have a question: is  it possible to filter a report by filtering a multi-select lookup with ID?

For example: Url/Multi-Select_Lookup_Field =" + input.ID + "..." ? Since the multi select lookup is a list and the input.ID is only one ID, could it work? basically my filter would work as a "Multi select lookup CONTAINS input.ID".

Thanks!
