[rules-users] Error accumulate function

[nestabur]

Solved!

I changed the accumulate function call for this one:

Number(intValue >= 1) from accumulate( fact() over window:time(1d)  from
entry-point "MyEntryPoint", init( mytotal = 0; ),action( mytotal++;
),reverse( mytotal--; ),result( mytotal; ))
