Correct PHP Syntax

Just a quick question -

html .="<param name=FlashVars value='imageFilename=$row[pic]'> "

As I don’t think the $row[pic] should appear within the ’ ’ think it should be somthing like this:

html .="<param name=FlashVars value='imageFilename='.$row[pic].'> "

but am not sure of the correct syntax.
