Any ideas/suggestions?
thanks advance

graceHi,

ORA-01741: illegal zero-length identifier is raised because, an attempt was made to use two double quotes ("") as an identifier.

An identifier must be at least one character long. Action: Insert at least one character between the double quotes in the identifier. If a blank identifier is required, specify a blank space between the double quotes (" ").sql
