Dynamic query

I new in this forum and I have a question about a problem for build a dynamic statement. My problem is when try to run my code from ASP or any app I have a error, I don't know that is bad in code, please below my PL*SQL. I'm not expertise in oracle but I try. Basically my problem is in the LIKE statement maybe I declared bad this sentence. The common code errors when try to load my query from asp are: ERROR-ORA-01756
ERROR-ORA-00911
I appreciate your comments and recommendations
