SSRS Expression help

Hello Team Members,

I have a location address field in my tables.the values are like this

1234 US 285 N, TX, TX 73450
24 CR 452 Orla, TX 79770
4536 U S 285 N
4536 U S 285 N TEXAS

I Want to split these fields using , operator

1234 US 285 N = location
TX            = State
TX 73450      = Pincode

=Split(Fields!Location_address.Value,",").GetValue(0)
=Split(Fields!Location_address.Value,",").GetValue(1)
=Split(Fields!Location_address.Value,",").GetValue(2)

I am using above expression for these fields but am getting =Error value if the location or state or pincode fileds are not available.

Please help us anyone give me the correct expression for this 

Thanks!
