because selector is incorrect. Why you added semi-colon in between tag and aaname property. Delete semi-colon and also change single quotes.
copy paste below one and try once. After copied it delete single quotes and then again add it.
aaname = ’ “+ row(“RelatedAuthors”).ToString+” ’
put one message box activty and print the value of row(“RelatedAuthors”).ToString before performing that click activity. Then check what value is coming from excel.
- <html title='Create Articles' />
<webctrl tag='LI' aaname='Raymond Man' />
first check this selector is valid or not. Validate it and then Highlight.
