crontab/current directory error

Dear all,

I have a command, it works if I in same directory

for example

mono /home/yapay/WebGrab/WebGrab+Plus.exe "$(pwd)"

works only if current directory /home/yapay/Webgrab is. If not I get this error:

config file /home/WebGrab++.config.xml doesn't exist
execution stopped

I would lik to execute this command with crontab but I am getting error because of this reason. How I can solve this
