An Access OnFormat Procedure Would Be Replaced In SQL Reporting Services By What?

In the field, the operators are presented with 5 categories, each category having between 3 and 5 possible selections, for example:

Weather - clear(1), cloudy(2), rain(4) or snow(8).

If the operator selected cloudy and rain, the value of Weather would be 6.

I want to print a report in the office that will list the categories and the available selections for each, putting an "X" next to those selections that were checked by the operators.

In Access, it was easy - I plugged a decode procedure into the OnFormat event...



cnum = obj![WEATHR]
If cnum - 8 >= 0 Then
obj![SNOW] = "X"
cnum = cnum - 8
End If
If cnum - 4 >= 0 Then
obj![RAIN] = "X"
cnum = cnum - 4
End If
If cnum - 2 >= 0 Then
obj![CLOUDY] = "X"
cnum = cnum - 2
End If
If cnum - 1 >= 0 Then
obj![CLEAR] = "X"
End If



Making the change to SQL Reporting Services, I'm clueless...as you can tell, I'm not even sure how to ask the question.

Any help would be greatly appreciated.
