Hi, Please read the forum posting rules about code tags...

And it might help a lot if you posted WHAT error you got. And did you search the forum (and read the migration documentation about the models used in the menus?)

ok thanks where i can get the migration documentation about the models used in the menus?

[kukeltje]

well, you can find it at least via here

And reading the blog now and then might also help

(and yes, it might have been easier to find via the basic site)

thank you kukeltje for the migration form .can u help me with the menumodel well i'm a newbie.please help me to create a menumodel

There have been posts about the differences between the 3.5 and 4.0 model in this forum, so you might be able to find things there. Since I personally do not use the models I have to digg into it myself as well, for which I do not have the time (nor do I want to 'create' the time, lots of other things to do, sorry).

Others might be able to help you out.

And do not forget my other question... Posting WHAT goes WRONG helps others a lot... Believe me, they will not try to find your error without that info... And please edit your initial post, using code tags AND correct indentation (use preview to check)

You have been asked, politely, to read the forum rules and use code tags to format the code you post. I am asking you, again politely, to do so.
Using code tags is not us being fussy, it makes your code much easier for us to read. Without this you will find people, like me, won't be prepared to make much effort to help you.
