error message after published new recipe

Hi,

i become a error message after I publish a new recipe. I have modified the recipe module but I don't know where comes the message from: The message:

Notice: Undefined property: stdClass::$recipe_instructions in recipe_insert() (Zeile 208 von /www/htdocs/www/test/sites/all/modules/recipe/recipe.module).

can you help me to solve this problem?

kind regards
drew
