Qty Discount display problems

I have add 5 qty discount
but it doesnt display in the products page.
anyone know what's the reason?

You probably put the data into the fields while the admin page was in "VIEW" mode.

You must click the "EDIT" button, then insert the data.

Oh,I have click the 'edit' button and fill the 5 blank Qty Discounts,and click the 'update' button,
but it doesnot display in the products page.

Have you checked the settings in ADMIN>>>CONFIGURATION>>>LAYOUT>>>:
*
Product Discount Quantities - Add how many blank discounts?
Product Discount Quantities - Display how many per row?*

You could have a faulty PHP file. We'll need to see a link to your site to help further.

I have checked it as follow.
Product Discount Quantities - Add how many blank discounts? 5
Product Discount Quantities - Display how many per row? 5

pls see this test link:http://www.szhif.com/hello-kittyc90-cute-pink-lady-phone-hello-kitty-series_p979.html

And if you switch to the Classic Template does it show?

If so, you have a template issue ...

I can see the beginning and ending tags for the:
Quantity Discounts table

in the view source ...

Oh,I have delete the classic template,
As you said, what is the fault file maybe

Removing the Classic Template really poses issues for testing for problems with your template ...

This could be several things ...

I'd first look at the product _info file for:
/includes/templates/template_default/templates/tpl_product_info_display.php

Compared to your file:
/includes/templates/your_template_dir/templates/tpl_product_info_display.php

And see what has happened to this code:

<!--bof Quantity Discounts table -->
<?php
  if ($products_discount_type != 0) { ?>
<?php
/**
 * display the products quantity discount
 */
 require($template->get_template_dir('/tpl_modules_products_quantity_discounts.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_products_quantity_discounts.php'); ?>
<?php
  }
?>
<!--eof Quantity Discounts table -->

<!--bof Quantity Discounts table -->

			<?php

			  if ($products_discount_type != 0 || $categories_discount_type != 0) { ?>

			<?php

			/**

			 * display the products quantity discount

			 */

			 require($template->get_template_dir('tpl_modules_products_quantity_discounts.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_products_quantity_discounts.php'); ?>

			<?php

			  }

			?>

			<!--eof Quantity Discounts table -->

This is my template code.

If you go to the Product Price Manager ... what is the Product Discount Type used by this product?

How many do you have?

If you look at your template file for:
tpl_modules_products_quantity_discounts.php

Are you using an override or the default?

I have click the 'edit' button and fill the 5 blank Qty Discounts,and click the 'update' button in admin.
tpl_modules_products_quantity_discounts.php

If you go to this Product in the Product Price Manager ... what do you have set on the:
Discount Type:
Discount Priced from:

percentage price

Very Odd ...

I can reproduce your error if I change the Discount Type to None and then I do not get the Discounts to display and only have the tags ...

If you go to that Product ...

What happens if you rename your template on the server to:
/includes/templates/lightinthebox_HIDEME

and refresh the page?

NOTE: things will look all squirrely when you do this ... the point is does the Discount Quantities show?

Then rename your template back to restore your current look from:
/includes/templates/lightinthebox_HIDEME

back to:
/includes/templates/lightinthebox

I have do that as what you said ,and when I rename it and refresh.
Warning: main(includes/templates/template_default/sideboxes/tpl_categories_css.php) [function.main]: failed to open stream: No such file or directory in /home/mov700/public_html/szhif/includes/modules/sideboxes/lightinthebox/categories_css.php on line 30

Despite that error ... could the screen draw?

If so, could you see the Discount Quantities?

It also didnt display.
but when I bought 5 or 10 products, It calculate as the discount that I set.
It only didnot diplay in the products pages.

Without going through your site to see what is wrong with your files this is really hard to break down ...

You might try Beyond Compare from scootersoftware.com and see if you can see any differences in the files from a clean checkout vs the files that you are using ...

There is also a Debug Tool in the Free Software Add Ons that might help spot this issue ...
