Set Analisys, take element withouth another

[danosoft]

I want to do this set analisys taking a value from my list box, when i choose "CESSAZIONE" in my list box:

this work:

//Sum({<DATA_OUT={"=Aggr(Max(DATA_OUT), MESEOUT, COD_PUNTO)"},STATO_OUT={"CESSAZIONE"} -  {'SCADENZA'}>} CONSUMO_TOT_ANNUO),

but i need to put the element of my list box, i tried in this way, but it not work, where is the problem?

    Sum({<DATA_OUT={"=Aggr(Max(DATA_OUT), MESEOUT, COD_PUNTO)"},STATO_OUT={"GetFieldSelections(STATO_OUT)"} -  {'SCADENZA'}>} CONSUMO_TOT_ANNUO),

use $(=) to evaluate function

try below

  Sum({<DATA_OUT={"=Aggr(Max(DATA_OUT), MESEOUT, COD_PUNTO)"},STATO_OUT={"$(=GetFieldSelections(STATO_OUT))"} -  {'SCADENZA'}>} CONSUMO_TOT_ANNUO),
