enabling and disabling combo boxes

[redblaze]

i have a series of combo boxes on a form for which 2 need to be disabled....

combo 1 has to be entered in order for combo 2 to display its contents, which in turn is needed for a list box to display its contents. i need to be able to disable combo 2 until combo 1 is entered, and list 3 until combo 2 is entered... if this makes sence to anybody do u know how it can be done?!

thanks in advance!

I suggest that you ensure the default value of your combo boxes is Null or "". After each step or click before, during and after the process (which ever works for your situation), you need to again make the value of your combos Null or "".

Now you can use the OnClick event of your combos or lists to test if Combo1 or Combo2 or what ever is Null and if true give them a message that they have to complete ComboX before they can use ComboY?
