[Tex/LaTex] Arrows in TikZ tree


I've been trying to create a tree consisting out of parents and nodes connected with arrows. I have created almost what I had in mind, except from that the arrows point the wrong direction.

could anyone be of help here?

label distance=3mm,
every label/.style={blue},
event/.style={rectangle,thick,draw,text width=3cm,text centered,anchor=north},
edge from parent/.style={very thick,draw=black!70,-latex},
edge from parent path={(\tikzparentnode.south) -- ++(0,-0.50cm)-| (\tikzchildnode.north)},
level 1/.style={sibling distance=4cm,level distance=1cm,growth parent anchor=south,nodes=event},
level 2/.style={sibling distance=4cm},
\node [event] {result}
    child {node {cause1}}
    child {node {cause2}}
    child {node {cause3}
        child{ node {subcause31}}
        child{ node {subcause32}}
        child{ node {subcause33}}

Replace -latex in edge from parent style with latex-.
