How can I build Combobox with 2 dimesnions?
I will use it as help screen but with more than 1 field and accept one field in the end of the choice :

eg.
Name address
S X
S2 X2


in the end of the chosing I will accept one value to filter my DB
eg. Name field .
Thanks

You can compose the combobox items using two or more fields and then get the position of the choosen item using oCbx:nAt.
