Constraining combo box values based on the value selected in another combo box

[philvalko]

Thanks in advance for your help.

I would like to set up rules/constraints such that the value selected in combo box A determines the available values in combo box B. For example, "Combo box A" is bound to the [PartnerType] field and "Combo box B" is bound to the [PartnerRole] field. Let's say that the two choices in Combo Box A are "LLC", "LP", and "Corporation". There are 5 possible choices in Combo Box B: "X", "Y", "Z", "Q", and "U". If a user selects "LP" in Combo Box A, I would like Combo Box B to only show choices "X" and "Y". And if a user selects "LLC", only choices "Y", "Z", "Q", and "U".

Similarly, I would like to set this up so that Combo Box B is not initially visible--it becomes visible when a user selects "LLC" or "LP". If a user selected "Corporation", Combo Box B would remain hidden.

This is typically refered to as "cascading" combo boxes. Searching on that should turn up several methods.

Thanks Paul. Not knowing all the correct terms for things has made it a bit tricky to hunt up the proper info.
