How do I make chocolate for a chocolate fountain?

[jonylovet]

I have a chocolate wellspring and a gathering tomorrow so need to get it running. I purchased a burden of Cadbury's Dairy Milk yet I realize that I would not be able to just stick it all in. I conjecture I dissolve it all seperately then include it in the wellspring. Does anybody know amounts and what different fixings I need to augment make the chocolate more runny? Much appreciated
