I have a query with parameters and i want to change the parameter value with
TIB_comboBox. I set up datasource for TIB_ComboBox and in paramname property
i entered correct name of parameter. Current value of parameter is showed
properly but i can not change the value.

So, how can i use TIB_ComboBox for updating parameter value of TIB_Query

SELECT PONUDE_ID
, PONUDE_DATUM
, PONUDE_OPIS
, PONUDE_ODOBREN
, PONUDE_DKO
, (PONUDE_JC * PONUDE_BV) AS VRIJED
, OPSTINA_NAZIV
, PROVIDER_SN
, TERSAR_IME
, VRSUSL_OPIS
FROM PONUDE
JOIN OPSTINE ON (PONUDE_OPS=OPSTINE.OPSTINA_ID)
JOIN PROVIDER ON (PONUDE_SP=PROVIDER.PROVIDER_ID)
JOIN TERSAR ON (PONUDE_TER=TERSAR.TERSAR_ID)
JOIN VRSUSL ON (PONUDE_VU=VRSUSL.VRSUSL_ID)
Where (OPSTINA_NAZIV Like :opstina) and
(TERSAR_IME Like :saradnik) and
(VRSUSL_OPIS Like :usluga) and
(PONUDE_DKO Between :oddana and :dodana) and
(PONUDE_ODOBREN Like :odobren)

:odobren can be in the ( 1,0,% ) list of values
