Multivariations are not available in all categories.  If it doesn't show under the category on the listing page it may not be available for your items.

Also, if you are using Turbolister, it does not support multivariation listing.

Hi enchantedfairies,

At this time, the Multi-Variation Merger tool as been discountinued and is no longer available.

To correct the previous reply, Turbo Lister does have the abilty to create Mult-Variation listings on the ebay.com.au site for certain categories.
