Hi, i am trying to get the following to work via kibana in a scripted field but all it causes is errors (not very descriptive), pretty sure this is an elasticsearch misunderstanding so posting it here.

example events [{ 'name': 'Name One', 'cash': 100}, { 'name': 'Name One', 'cash': 24}, { 'name': 'Name Two', 'cash': 112}]

def rtp = ['Name One': 0.986f, 'Name Two': 0.94f];  
def name = doc['name'].value;  
def rtp\_val = rtp[name];

def win\_pct = 1 - rtp\_val; // errors  
def cash = doc['cash'].value;  
def win\_amt = cash \* win\_pct; // errors but mainly due to first one.  
return win\_amt;

Only thing i can think of is that the error is something related to types so looked around trying to find a way to convert to floats, the only example i did end up finding doesn't work and is quite old, pretty sure it's a groovy example.

Float.parseFloat(rtp\_val); // errors

Any one know how to achieve this ?

P.S would be nice to have kibana show an example output from a random event

Thanks
