First off, I suspect that the problem is caused by "Option Explicit", which is probably not supported by VB Script (as that is a compile-time option, and VB Script is interpreted instead of compiled).
Next up, why are you trying to delete a system table from a database? If it works (hopefully it wont), that will probably cause severe problems.
actually i am not deleting database.... my MDB data file had error, "AO not in index"... i just saw that program on website... and they advised that i should make a script like that.. so that i can copy my database to another database so i can access it... if you knew already same problem with me.. can you assist me on my error...
Deleting a system table is a very bad idea, as the system tables contain the information needed to make the database work (such as what tables are in the database, and which field is in each, etc etc). Deleting any of them will almost certainly make the problem much worse.
If you really know what you are doing, modifying the data may work - but if you don't know enough (or you make any mistakes), the problem will again be likely to become worse.
The route I would recommend is to perform a Compact and Repair on the database from within Access, as that should automatically correct the system tables (assuming that there hasn't been too much damage already).
