Source for 'Copy File' component

Hi

I am using the ‘Copy File’ component in my protocol and the source filename is a string ‘temp’ appended with the protocol parameter ‘filename’. Let’s say the protocol parameter ‘temp’ has a value ‘C:/Test/’ and filename is ‘TestFile.csv’. I would like to give ‘C:/Test/TestFile.csv’ as the source to ‘Copy File’ component. May I know how I could do this? Thanks.

Regards
