hbase - PIG dynamic parameters -

i trying read value hbase table , decalre value param

rawconfig = load 'hbase://mytable.config'       using org.apache.pig.backend.hadoop.hbase.hbasestorage(         'm:config',         '-gte mytsflag -lte mytsflag}'       ) (         tsconfig:chararray       );  rawcache = foreach rawconfig generate (isempty(tsconfig) ? '0':tsconfig) lastts; 

now want set value of rawcache.$0.lastts paramter can use while loading next table

this not work

%declare myconfig rawcache.$0.lastts; raw = load 'hbase://mytable.users'       using org.apache.pig.backend.hadoop.hbase.hbasestorage(         'm:1',         '-mintimestamp $myconfig'       ) (email:chararray); 

any ideas on how can use value of previous table?

am relatively new pig may wrong :).

quoting statement should work:

 %declare myconfig 'rawcache.$0.lastts'
