I am trying to debug this error:

`Ruby exception occurred: no implicit conversion of Float into String`

But i don't know what exactly means, no information about de field or line.

what is your ruby code?  
whatever field you are trying to change or reset in ruby is float but you are trying to do some string operation to it.
