what is reserved error (-3004) Ed Brown 22.09.2006 09:23:01 i keep getting this error when i try to input data in my database, from one table to another; anyone know what this error means. 3 tables running a music database first table is: Artist. next is: Album. the last is: Tracks. trying to input data into the tracks table from album table, and this is the error message i receive. is it possible that there's hyperlinks in the two tables: Album table has hyperlinks to full album play, and tracks table has hyperlinks to each albums track. all references are the same, and there's nothing different from one table to another. this worked at one point, but since the last office update (sp2) i've been having some trouble with Access.
