Creating a link to a file using 2 variables.

Hey,
Ok I'm on a web page, where 2 hidden variables, named ProgramName and SoftwareEstimateNumber, are set to "Test" and "3" respectively. Now I have a file I need to link to that has already been named "Test-3.xls" (another script does that and stores it on the server). What I need to do is link to that file based on whatever those hidden fields turn out to be. So in VB I figured I had to concantenate the 2 variables somewhat like so:

filestring = ProgramName & "-" & SoftwareEstimateNumber & ".xls"




So basically I have the directory set so my link would point to "/SWEfiles/filestring"

Can anyone show me how to code this right in an <A HREF> statement sended through using VB?
Thanx for reading my post and let me know if any further details are needed... =)
