The Reference qual script of a select box variable is set to get the choices depending on another variable. But it does not return the correct choices.

All

The probable cause might be because of having 'return' in the reference qual.

To resolve the issue, remove 'return' from the reference qual script:

Ex: Remove return from : "javascript:return 'u_test=' + current.variables.snc.getDisplayValue();"

and write it as : "javascript:'u_test=' + current.variables.snc.getDisplayValue();"
