HTML:Server Tag Not well Formed

Hi all I get the Server Tag Not Well Formed e开发者_运维问答rror on the following line of code.

<a class="button"><span><input id="btnEmbedCodes" type="button" 
value="Click for Embed Codes" onclick='javascript:window.open("%=ExternalLink%>","ExternalFeeds","height=575,width=675,
scrollbars=yes,overflow-x:hidden")'; Style="width:165px" /></span></a>

Please help me out. Thanks

window.open("%=ExternalLink%>"

In this starting "<" is missing. Seems like that is the problem.

It looks like you missed a < in the first argument of your javascript function

You are missing the opening bracket before ExternalLink

You have missed less than sign (<) before ExternalLink and also surround it with single quotes rather than double quotes.

Thanks.
