I have a batch script in which i am using multiple if exist statement, the problem is all statements are working except one .

Following variables are set

SETLOCAL ENABLEDELAYEDEXPANSION
SET basedrive=E:
SET tfworkspace=!basedrive!\TFS
SET envdefault=%1
SET projenv=!envdefault!
echo subapp=!subapp! subappservice=!subappservice! 
SET tfworkspacepath=!tfworkspace!\!releasebranch!\!app!\!subapp!
SET tfworkspacepathservice=!tfworkspace!\!releasebranch!\!app!\!subapp!\sourcecode\build\!projenv!

This statement works,

if exist "!tfworkspacepath!" (robocopy "!tfworkspacepath!"\sourcecode\messagebroker\ /E /NFL /NJS /NDL /ETA  "!basedir!\!messagebroker!" )  else SET /a foldererror=1

This statement doesn't work, by does not work i mean even thou the path does not exist it it still tries to robocopy.

if exist !tfworkspacepathservice! (
  robocopy !tfworkspacepathservice! /E /NFL /NJS /NDL /ETA  "!basedir!\!scripts!") else  SET /a foldererror =!foldererror!+1

I am new to batch writing, please guide me
