Correlation web_reg_save_param_regexp

I am using VuGEN 11.52 and i am having some problems whit the web_reg_save_param_regexp i need to correlate the value "2921674"  but i find it in 2 differents urls:

1) http://207.248.191.52/develop/index.php?page=inscripcion.agregarInscripcionGeneral&idpersona=2921674&primeraopcion=356&id_periodo=281",

2) http://207.248.191.52/develop/index.php?page=inscripcion.tiraMateriasGeneral&id_alumno=2921674&id_periodo=281",

The automatic correlation is:

web_reg_save_param_regexp(
"ParamName=CorrelationParameter_2",
"RegExp=idpersona=(.*?)&primeraopcion",
SEARCH_FILTERS,
"Scope=Headers",
"IgnoreRedirections=No",
"RequestUrl=*/index.php*",
LAST);

but this correlation only works for url number 1, how I can make it work for both urls??

The error i'm getting is: No match found for the requested parameter "CorrelationParameter_2". Check whether the requested regular expression exists in the response data 

Thanks in advance!!!
