help with illegal offset warning

[dsp77]

im working in modifying interspire cart to show the dimensions to but i get this error  Warning: Illegal offset type in includes\display\ProductDetails.php on line 39 the code from that line is  if($product[$dimensions] > 0) { and the full code:

$product = $GLOBALS['ISC_CLASS_PRODUCT']->GetProduct();
$dimensions = array(
    'ProductHeight' => 'prodheight',
    'ProductWidth' => 'prodwidth',
    'ProductDepth' => 'proddepth'
);
foreach($dimensions as $global => $field) {
    if($product[$dimensions] > 0) {
        $GLOBALS[$global] = FormatWeight($product[$field], false);
        $hasDimensions = true;
    }
    else {
        $GLOBALS['Hide'.$global] = 'display: none';
    }
}

if(!isset($hasDimensions)) {
    $GLOBALS['HideDimensions'] = 'display: none';
}

I'm not quite sure what you are trying to do, but did you mean to reference $global (the foreach iterator) instead of $dimensions?

 

That may help your code execute, but you would be checking to see if each assigned string is greater than 0, which doesn't make sense.

 

Hope this helps... if not maybe you can explain what you are trying to accomplish.

error mean: You try $product[$dimensions] - but variable $dimension is array!
