Sql: Incorrect syntax near the keyword "as" - sql

Question

I have the following query. I'm not sure why it says the error in the title. I marked where is the error.
SELECT cmp.idcampanie,
spt.idspot,
spt.alias,
perioada =
(SELECT perioada
FROM dbo.tf_formatperioada(spt.datainceput, spt.datasfarsit)),
tipprogramare = tipprg.nume,
ora =
(SELECT ora
FROM dbo.tf_formatora(spt.ora, 0)),
spt.aliasex,
durata =
(SELECT durata
FROM dbo.tf_formatdurata(spt.durata)),
spt.coststandard,
spt.cost,
spt.nrdifuzari,
spt.valoare
FROM dbo.campanii AS cmp CROSS apply
(SELECT idspot, ALIAS, datainceput, datasfarsit, orafixa, tipprogramare, ora, aliasex, durata, coststandard, cost, nrdifuzari = sum(nrdifuzari), valoare = sum(valoare)
FROM dbo.tf_costurispoturi(cmp.idgrupmedia, cmp.idcampanie, cmp.datainceput, cmp.datasfarsit, cmp.idoferta, cmp.coeficienticostduratespoturi, cmp.coeficientcost, NULL)
WHERE idcanalmedia IS NOT NULL
GROUP BY idspot, ALIAS, datainceput, datasfarsit, orafixa, tipprogramare, ora, aliasex, durata, coststandard, cost) AS spt
INNER JOIN dbo.tipuriprogramari AS tipprg ON tipprg.orafixa = spt.orafixa
AND tipprg.tipprogramare = spt.tipprogramare
WHERE cmp.idgrupmedia = 1
AND cmp.datainceput <= '5.01.2014'
AND cmp.datasfarsit >= '5.30.2014'
ORDER BY cmp.idcampanie ASC,
spt.ALIAS ASC, spt.ora **AS spt** COMPUTE spt AS sptdtl BY idcampanie,
idspot,
ALIAS,
perioada,
tipprogramare) RELATE idcampanie TO idcampanie) AS spt

Answer 1

it gives error in order by
ORDER BY
cmp.idcampanie ASC,
spt.ALIAS ASC,
--spt.ora **AS spt** COMPUTE spt AS sptdtl
BY idcampanie,
idspot,
ALIAS,
perioada,
tipprogramare
)
RELATE idcampanie TO idcampanie) AS spt
Except this query is not give error, see query as below.
SELECT cmp.idcampanie,
spt.idspot,
spt.alias,
