Crystal Reports Looking for a little help writing this formula

Message

     My database looks something like this

          Table 1                                               Table 2
Case  Physician Code     ------->   Physician Code   Name
 123            1                                             1             Dr Smith
 123            2                                             2             Dr Roberts
 124            1                                             3             Dr Jones
 125            1

and so on ....

I would like this to show up as

Case    Physician1     Physician 2 
123        Dr Smith       Dr Roberts
124        Dr Smith
125        Dr Smith

I brought in table 2 twice and aliased it as Table2_1.

@Physician 1 = if {Table1.Physician_Code} = 1 THEN {Table2.NAME}
@Physician 2 = if {Table2_1.Physician_Code} = 2 and {Table2.Physician_Code} = 1
THEN {Table.NAME}

What I get is

123   Dr Smith
123   Dr Smith           Dr Robert
124   Dr Smith
125   Dr Roberts

How can I eliminate the "duplicate" lines where the data fits the condition of having a value for Physician 1.  Does it have anything to do with a whileprintingrecords formula?

Thanks for the help!
