Populating Combo Boxes based on another value

[Guest]

I am not quite sure how to make this happen. I want to populate a ComboBox
based off the value entered for the first ComboBox. I have 2 field names
species and strain. I would like to make it so when a user selects a type of
species, only the corresponding strains show up in the 'Strain' ComboBox. I
cant quite get it to work. Any suggestions???

Do a search. This is asked and answered all the time. Look for "cascading
combo".
