Can someone please give guidelines on how may I start with database driven dependent drop down box? Should I have to create a lookup fields in the database or just populate all the required fields? how will I retrieve the records using asp?

I have four fields -when select a value, second box should be populated based on the value chosen and so on, I would like to store all the required information in the database, then pull those data using asp.

You can use this code if you would like.

And perhaps this may hopefully give you some ideas. It's got a downloadable sample and does retain values after the post back:

Thankyou freeasphelp. If possible, can you please explain the coding part? And in database, should all the data be manually entered in to the database?

I have one more question regarding the database. I noticed that CountryID field in Countries table is Autonumber and under properties - Fieldsize = Long integer , New Values = Increment. In State table, countryId as Foreign key, you have given CountryId as Number and under properties - FieldSize = Long Integer, Decimal Places = Auto and default value = 0.

My question is:
1.Will Access allow to set different datatype for the relationship fields because I have tried doing it but when it comes to setting the relationship, it always gave an error.

I would like to use this code (aspchain.zip from above) for the dynamic list but I'm not sure how to insert data into a table that has relationships, like if I want to insert the model, make, year and options of a car how would I do that, I know how when just using one table just not two?

Thanks for any help you may have.
