[split] Help with popup window?

One last thing, I noticed that on the 'add_more' link your view is creating something like the following:

Code:

<div float:right; font-size:11px; margin-top:2px; " align="right">

should be more like:

<div style="float:right; font-size:11px; margin-top:2px; " align="right">

So that is why you are unable to open a newly created appointment. You are missing (for some reason) a bit of markup. To find this I just looked at the console and it showed me the exact line causing the error.
The previous error mentioned above is on the 'add_new' link, not the 'add_more'.
You may have more problems, or it might be a simple cut and paste error in a view. 
I hope that helps,
Best wishes,
Paul.
