UI Macro/UI Page to get KB URL (button with link) next to a field

[Hari7]

UI Page:

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	<a href ='/kb?id=kb_article_view&sysparm_article=KB0021078'target='_blank'>Click here to know about Story Points</a>;
</j:jelly>

Error Message: Error at line (3) The reference to entity "sysparm_article" must end with the ';' delimiter.

Referred this Error Message in Hi Support KB Article and there seems to be property to be set to true and this is already true.

Also, tried changing & to &amp, %26 but nothing worked. Any help on this is much appreciated

Also @Hari7 try this 

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	<a href="/kb?id=kb_article_view&amp;sysparm_article=KB0021078'target='_blank'>Click Here</a>;
</j:jelly>

let me know if this works 

You can also try this by controlling few properties which i mentioned in other response
