What are you attempting to do with your code?
If you're just trying to see if a recordset has values you can do something like with dcount or, since you already have the SQL statement you can do this:
Code:
dim db as database
dim rst as recordset
set db = currentdb
set rst = db.openrecordset(ssql)
if rst.recordcount <> 0 then
<set the enabled property of your combo box to true>
else
<set the enabled property of your combo box to false>
endif
rst.close
set db = nothing
You'd just have to fit it into your existing code after you establish the SQL string.
Or are you trying to build a SQL statement using 1 or more combo boxes as input and are trying to adjust your WHERE statement accordingly? You reference cboDesc2 and cboDesc3 but they appear nowhere in your code.
