Link to entry with child problem

[fufu...@gmail.com]

I do many useful things such as creating database for my shop with memento and its a great apps.

My problem is after doing the same tutorial in the section link to entry example 6 in memento PDF.
the error said: cannot resolve variable with name equal to "item.price"

I have 2 libraries:
Library Order > order (link to entry) item, count(integer), sum(calculation) #{count} * #{item.price}
Library Item> item(text), price(integer)
my item and price are earth USD5000, mars USD7000, pluto USD9000 and i have insert the count field to 2
Am I doing something wrong with the link field? and why it can't load the price data??

Example 6:
There’s library Order – with orders and library Item – with items.
Library Order contains a link to library Item and numeric field Count .
Library Item contains field Price .
To calculate the cost of the order, let’s add calculable field Sum using the following
formula: #{count} * #{item.price}

sorry it's my bad, i already find the problems, that's because of my memento's version. It works fine now after I update to new version, thanks for the forum.
