Question about chaining

I'd like to be able to have two separate chains off of one control. Is there any way to do this in the HTML tool?

Example:

Country->Cars->Sales
Country->Model

When the user selects Country, Cars should be filtered based on the newly selected and model should be filtered based on the newly selected country.

Right now, when I already have the first chain set up and I just select Country and Model together and chain them, Model becomes item number 4 on the first chain as opposed to item number 2 of a second chain.

Is there anyway to do this?

Yes, but not using the Master files for combo box population. Use fexes instead because then you would only add the selection on the variables you want -

fex for model
TABLE FILE CAR
.....
WHERE COUNTRY EQ '&Country'

fex for car
TABLE FILE CAR
.....
WHERE COUNTRY EQ '&Country'

fex for sales
TABLE FILE CAR
.....
WHERE COUNTRY EQ '&Country'
WHERE CAR EQ '&Car'

Tony,

Thanks that works great. I have one more interesting scenario, though, that I should have added on to begin with.

There is another control at the end of the chain.

Using the previous example:

Country->Cars->Sales
Country->Model

The last control would be for example, RETAIL_COST that should get updated if either chain gets updated. If it's the first chain then I'd want RETAIL_COST to be filtered based on all the filters of the first chain and if it's the second chain, then all the filters of the second chain. I can potentially know which "state" I'm in by having the user select from a radio button on the page to let me know that "chain 1 is in use" or "chain 2 is in use". Am I asking for too much here?

On a slightly different topic - I've noticed that once I've used a procedure to populate a control in a chain, any controls below that in the chain will not get populated if I want to populate it dynamically from the database. Am I doing something wrong or is that just a fact of life?

Thanks.

Actually,

Just as I'm thinking about my first question - I guess I could take your idea and use the radio button selection to decide which 'WHERE' statement to include for populating the RETAIL_COST control and that should be good!

I always stick to fexes for population of combos as it is more controlable.
