Subject:	Using subArray record

Hi all. Im trying to use the subArray method to select a single element of a waveform record. The waveform record receives its value from an scalcout record:

record(scalcout,"PREFIX:GetRngCalc") {

field (DESC, "Calculate channel's range")

field (INAA, "PREFIX:GetRng CP")

field (CALC, "(AA-'RNG ')")

}

record(waveform, "PREFIX:GetRngWav"){

field (DESC, "Waveform for ranges")

field (INP, "PREFIX:GetRngCalc.SVAL CP")

}

after the ioc initialization:

dbpf PREFIX:GetRng "RNG 0 1 2 3"
dbgf PREFIX:GetRngWav
DBR_STRING: "0 1 2 3"

So i suppose it works. However, when i try to add the record:

record(subArray,"PREFIX:INDEX:GetRngCalc") {

field (DESC, "Calculate channel's range")

field (INP, "PREFIX:GetRngWav CP")

field (MALM, "4")

field (NELM, "1")

field (INDX, "1")

}

And i try:

dbgf PREFIX:INDEX:GetRngCalc

I get nothing. Am i doing something wrong?
Thanks in advance for any help.

My ioc initialization:
