[ic] problems with the [if] Statement

[Jonas Hoffmann]

Hi !

I have problems with the if Statement.

I have some products in the products.txt with some empty fields like this :
sku     description     price   image   category        display beschreibung  
  einheit saeure  restzucker   alkohol jahrgang        auszeichnung    lage
36      Rondo Tafelwein trocken 0,75 Ltr.       11.00           Rotwein  

Now i want to let some fields empty in my flypage if there are no values in 
the products table, here is what i try but it doesnt work :(


[if item-restzucker eq ""]
	<td  class="TabHeadEinzel">[item-field restzucker] g/Ltr.</td>
[/if]

i tried some others also but it doesnt work :(
