Posting a Value to a Combo Box

[biffer711]

I'm trying to load a saved record from a table into a form. All of the data comes in nicely except for my Combo Box, which doesn't seem to be able to accept the value the way I'm referencing it. I'm trying to use the assignment Combobox.value = "Bloom". "Bloom" is one of the existing elements in the Combo Box. There is no change in the Combo Box and when I do a msginfo immediately following the assignment the Combobox.value is equal to the value that existed in the Combo Box prior to the assignment

I'm very new at this, so I'm sure there must be an easy answer.

Thanks
