SSRS Report Expression, for 2 fields in one column

Question

I'm creating a report, and I'm trying to have two fields displayed one or the other in the one column= Account Name.

See my problem is, if I run the report with one of fields some some of the account names are populated

For example:

Table 1

Table 2

If I use 1 set of Account Name and Address fields, only some Name/Address fields are populated like in Table 1.

If I use the other set of Account Name and Address fields, only some Name/Address fields are populated like in Table 2.

How can I use the 2 sets in an Expression, so that all the Name/Address fields are populated.

Answer 1

I've solved it,

=Fields!Addr1.Value & IIF(IsNothing(Fields!Addr2.Value),"",VbCRLF & Fields!Addr2.Value)
