Hello Sergey!
Sorry, but here i am again.
Just for understanding ??

This code at InteractiveChange event of a search field works as expected:

local l_verbindungsnr,l_cursor,l_select
l_sucher = "%" + alltrim(this.value) +"%"
l_verbindungsnr = -1
l_cursor = "adressauswahl"
l_select = "select adressnr,name1,plz,ort from t_adressen adressnr where name1 like ?l_sucher"

*öffnen der verbindung
do p_oeffnen in p_funktionen with l_verbindungsnr

*wenn verbindung ok !!
if l_verbindungsnr >= 0
do p_lesen in p_funktionen with l_verbindungsnr,l_select,l_cursor
ENDIF

select (l_cursor)
browse


but the same code with defining
local l_sucher,l_verbindungsnr,l_cursor,l_select
........
there is always a popup window "Please enter a value for l_sucher"

Just for understanding, whats wrong with "local l_sucher"

Best regards
Albert
