writing an expression that would do a vbcrl

Hi all

I have a column (ColumnC) in an access query which extracts the notes from column A and ColumnB and seperates them with a comma.

This is the expressoin I use in access (Note: [RecheckNote] & IIf(Not IsNull([RecheckNote]) And Not IsNull([CTNote]),",","") & [CTNote] )

What I would like is to write an Expression in RDLC report that everytime it encounters a comma it would do a line return and Put "-" after the line return.

Can someone help with this situation

Thanks in advance
