Okay, I managed get all the values by making the template file like so:
<!-- MapServer Template -->
{
"CORGADBAU": [value_0],
"CORGADSSM1": [value_1],
"CORGADSSM2": [value_2],
"CORGADSSM3": [value_3],
"CORGASRBAU": [value_4],
"CORGASRSSM1": [value_5],
"CORGASRSSM2": [value_6],
"CORGASRSSM3": [value_7],
"CORGRDSSM1": [value_8],
"CORGRDSSM2": [value_9],
"CORGRDSSM3": [value_10],
"CORGRSRSSM1": [value_11],
"CORGRSRSSM1U": [value_12],
"CORGRSRSSM2": [value_13],
"CORGRSRSSM2U": [value_14],
"CORGRSRSSM3": [value_15],
"CORGRSRSSM3U": [value_16],
"CORGSOCBAU": [value_17],
"CORGSOCSSM1": [value_18],
"CORGSOCSSM2": [value_19],
"CORGSOCSSM3": [value_20],
"CORGSSMU": [value_21],
"CORGT0": [value_22]
}
