I have a variable called %SvnPathBranch% which can either be empty or have a value in it.

I&nbsp;have another variable call %SvnPath% which is set by default to "http:\\mypathtrunk"

if (%SvnPathBranch% is not&nbsp;empty)

{

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; %SvnPath% = %SvnPathBranch%

}

How can I do this?

Hi Peter,   
  
 Use the If…Then action with the left hand value as %SvnPathBranch% and leave the right value blank, then use a Set Variable action as a child action.   
  
 Regards,   
 Paul.
