I changed the code and this is the resolved:

thisform.malla.recordsource = ""
do consultas\conexionesact.qpr
thisform.malla.recordsource="conexiones_act"
count for tipo="Persona Natural" to thisform.totpn.value
count for tipo="Persona Juridica" to thisform.totpj.value
thisform.totalgral.value=thisform.totpn.value+thisform.totpj.value

count for tiponet="Intranet" to thisform.totintra.value
count for tiponet="Internet" to thisform.totinter.value
