RodneyLai,

First, the link format is not correct.

<a href="'>some URL">this is a test</a>

should be

<a href="some URL">this is a test</a>

Second,  "&" is a special character.

 

Cute Editor automatically convert it to html entity.

somepage.aspx?param1=3&param2=50

will ends up in html as

somepage.aspx?param1=3&amp;param2=50

By default Cute Editor maps most special characters to the equivalent HTML entity automatically. You can turn it off by setting Editor.UseHTMLEntities Property to false.

Hope it helps.
