Text label referencing a Dropdown is displaying text, but !isblank is returning value as True?

Hi everyone,
 
I'm a little confused at what is going on here. I have a text label that is returning the value that is selected from my dropdown box and it is correctly displaying the text. But when I try to pull a reference field that is based on an Excel table, the result is always blank. So I tried a debugging label and for some reason the !IsBlank() function is returning as "True" even when an item is selected, so I think this is the root cause of why I'm not getting any referenced values from the table. Any idea what is going on?

    Hey. Can I check the logic please?:
     
    !IsBlank(selectedVendor) = selectedVendor is not blank
     
    If selectedVendor has been set, then this logic is correct?

    So my VENDORID excel file has a bunch of "spaces" trailing and for whatever reason, PowerApps would automatically trim the ends in the Lookup function but still try to reference the field with trailing spaces. The following formula worked for me:
     
    LookUp(APVEN, VENDNAME = TrimEnds(VendorList.Selected.VENDNAME), VENDORID)
