Joomla Login Module is not redirecting to Hikashop

-- url of the page with the problem -- : www.mywebsite.com
-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.1

Hi Admin, i'm experiencing a serious problem with my Joomla Login module. My "Redirect Joomla registration to HikaShop plugin" is enabled but my joomla login module never redirects to the hikashop Plugin Login/Registration page. Instead it redirects to www.mywebsite.com.ng/affiliate/user/form when "create a new account" is clicked. If i unpublish affiliate menu,it redirects to www.mywebsite.com.ng/billing-address/user/form , if i unpublish billing address menu, it redirects to brand Menu www.mywebsite.com.ng/brands/user/form . it was changing from one menu item to the other. I unpublished almost all and left the Joomla registration menu & hikashop user menu of which it choose the Joomla reg Menu as its redirection page ( www.mywebsite.com.ng/sign-up/user/form ) yet it was still the same result. it just opens a blank page after "register" is clicked without any success or failure message. On my User Manager in the backend, it shows the User has registered.

Please, How can i make it to take the login menu i created or hikashop Registration form menu as its redirection page and also make it display a Success or failure Message for the registration.
I've done all i can to correct it but i don't know where the problem is coming from. Pls do help out. Below are screenshots. Thanks

OK, thanks Nicholas, filling the itemid no with the right menu number solved it.
My other question is
1)how can I make hikashop/joomla display a message at the top e.g. "Thank you for registering, you're now logged in", "Thanks for registering, you can now login", "wrong username/password", etc. Because at the moment, it doesn't display any error message when logging in fails or after successful registration. I will like a message to be displayed so that my customers can be carried along
2) For opera mini mobile browsers, when a new user registers, it doesn't log the user in automatically & also doesn't display any message of successful registration. It just brings up an empty registration boxes for the user to start all over & fill in their details. Meanwhile, on the backend, I can see the user details that they registered successfully. That's one of the major reason why I need it to display a response message like I asked for in 1) above. Been that 40% of my country's mobile phone users browse with opera mobile browsers, its not something I should overlook. Can't tell if its a joomla or hikashop issue but will really appreciate if you can help me out.
Thanks

Resolved. I mistakenly switched off system messages in my templates settings. Thanks

I have another question, pls how do I change the "Choose Options" button text displayed for custom item field in the frontend which redirects to the product page? I was able to change "add to cart" but couldn't find the "choose options" text. Will appreciate your help thanks

Worked perfectly. Thumbs up bro
