This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. So show us what the tables are, give us sampel data, explain what you expect to get, and tell us what the error actually is!

WITH AllTables (roba, kolicina) AS
(
SELECT roba,kolicina FROM MP_RACUN_ROBA
UNION ALL
SELECT roba,kolicina FROM mp_faktura_roba
)

SELECT roba AS 'Naziv artikla',
SUM (cast(kolicina AS float)) AS 'Prodata kolicina'
FROM AllTables AT
INNER JOIN mp_ulazni_racun_ostalo_roba MPU ON AT.kolicina=MPU.kolicina
GROUP BY roba

Msg 209, Level 16, State 1, Line 8
Ambiguous column name 'kolicina'.

Line 8 and I need in line one more table mp_ulazni_racun_roba

use alias name to select the column and will avoid Ambiguous column errors.
like - kolicina exists in AllTables table the change your select as AT.kolicina : to SUM (cast(AT.kolicina AS float)) AS 'Prodata kolicina'
