Mailing Labels In SQL Server Reporting Services

I am creating a report to be used to print mailing labels. Size 1" x 2 5/8" (3 columns of 10 labels). I seem to have everything but the vertical spacing working properly. I have used a rectangle set to the size of the labels which contains a list box containing text boxes containing expressions to pull in the fields. Some of the street addresses are two lines with the majority being only one line.



I have joined the two fields containing the street addresses and inserted a new line command so each field will print on its own line but yet be contained within the same text box. Everything except the text box containing the street addresses are set to not increase or decrease. My problem is that on the pages of the report where labels vary between the one and two line street addresses the labels tend to creep down which in some cases causes data to be printed over two labels. Any ideas on what I can do to format these to print properly?



Thanks
