Using variables and IF on popup hotspot

I'm trying to change the opening of a popup depending on the "lingua" variable but I just can't figure out how to do it ...
That's what I done and it doesn't work at alla (fatal error):

<hotspot name="spot2" style="infospot"
    	html="Web"
    	ath="0.000" atv="0.000"
    	onloaded="circlepos(2,5);"
    	onclick="if(lingua == 1, 
    	"popup('iframe', 'https://bosanza.com', 800, 600, true);","popup('iframe', 'https://gavdos.info, 800, 600, true);""/>

Thanks a lot for your help.
Matteo.
