access obfuscation – Blocked while editing a page

Any I idea I keep getting block, this is messgage:

Attack details follow :

- Variable 'content' of the POST method triggered the filter 'JavaScript location/document property access and window access obfuscation' for the content '<h2>Upcoming Event in the Next 10 days</h2>
[events events=10 days=11 listtype=1 cat=9 startoffset=0]
<h2>Services</h2>
[events events=10 days=7 listtype=1 cat=7 startoffset=0]'.

This is clearly the code from the page I’m developing, using amr event list. I use similar in other pages and widget without problem.
