Hi, Can someone please help me to find the mistake above ? I am getting an error as "Input string was not correct !"; Thanks in advance,

Your inline onClick handler has unescaped standalone braces in the object literal:

onClick=\"return hs.htmlExpand(this, { headingText: '{6} - {7}', width: 600, height: 215, targetX: 'row1 400px', targetY: 'row1 40px' })\">"

You need to write this, {{ headingText... }}
