My last topic of today, I PROMISE... you guys have helped so much...

ON my ratings script it goes from 1 to 10

heres what i want to do

If $rating is between 0 and 3 i want $img = "poor.gif"
If $rating is between 4 and 7 i want $img = "average.gif"
If $rating is between 8 and 10 i want $img = "good.gif"

heres the code i have but its not working:

// set smileys
if ($addrate <= 3) { $smileyimg = "sad.gif"; }
if ($addrate <= 7) { $smileyimg = "straight.gif"; }
if ($addrate <= 10) { $smileyimg = "happy.gif"; }

if ($rating <= 3) {$img = "poor.gif";}
if ($rating >= 4 && <= 7) {$img = "average.gif";}
if ($rating >= 8) {$img = "good.gif";}
