Guild Wars 2

so i got my 3 mini llama’s and the essence of llamatic elegance to forge the mini fancy llama. I put the three llama’s and the essence in but i cant forge, i get the following pic. Looks like i somehow need to “split” the 3 llamas to fill the 4 slots… anyone care to help?

Assuming you have the actual llamas in your inventory, simply press Alt and then click and drag the stack to split it.

did it and it worked thanks a bunch!
