ORA-02158: invalid CREATE INDEX option - when executing Collection in PL/SQL

My goal in the following proc is to accomplish the following:

1. Get index syntax of specific table
2. Drop and create table with new data
3. Create index for new table

I've been able to store index syntax in Collection variable IX_L with the help of BULK COLLECT INTO.

But I'm struggling with executing the CREATE INDEX that's stored there. When I loop through EXECUTE IMMEDIATE IX_L(i); I get an error ORA-02158: invalid CREATE INDEX option. But, when I execute the same exact text explicitly and not from withing the Collection variable it works fine, so it doesn't seem like there is a problem with my CREATE INDEX syntax.

I would appreciate any help.

          AND t.TABLE_OWNER = ''DWH''

          AND t.TABLE_NAME = ''TBL''
