E-Commerce Configuration Guide : Site Configuration Settings : ModOnModColLen : ShowModOnModsError
 
ShowModOnModsError
Key value:
Text indicating that additional modifiers must be selected for certain items
Description:
Set ShowModOnModsError to text to display when the correct number of second level mods have not been set when trying to add to cart.
The E-Commerce pages now support second level modifiers. When you have ShowModOnMods = 1 set in the siteconfig.config file, and you select an item that has first and second level modifiers, you get taken to the ItemShow.aspx page. Here, selection of a first level modifier that is configured with its own modifiers, automatically displays a popup window in which the second level modifiers are displayed. Once second level modifiers are selected on the popup dialog, the user needs to click on the Add Choice(s)/Verify Price button in order to update the price if needed and activate the Add to Cart button. If other first level modifiers that are configured with their own modifiers are selected, the second level modifiers are each displayed on the popup window. The popup window remains displayed on the page as long as there are first level modifiers selected that are configured with second level modifiers even after the Add Choice(s)/Verify Price button has been clicked. This allows the user to review the choices they've made before clicking the Add to Cart button.
 
Note: At this time, second level modifiers in E-Commerce module can only be configured as Regular Item, Item Type on the Action tab of the Item Edit Form in SysManager. In other words, second level modifiers cannot be configured to require a guest to be attached.
 
Support has been added to Sales Host utility to allow processing of multiple levels of modifiers.
Example:
ShowModOnModsError = Make the right modifier selections to get the item added to the cart.
