WF error in : Condition step ??

Hi All,

My condition step is not working fine , Pls help me out.

I am designing WF for parking invoice (tcode- FV60, BO -FIPP),there I need to give following condition:

If Invoice Amount > 2500 USD then mail is sent to some particular approver otherwise some other approver.

I have declared one variable 'Amount' in WF container with refrence to table- INVFO and field - WRBTR.(this is a currency field.)

and in condition step in WF, I am giving a condition .i.e - 'Amount' > 2500

After activating WF and while testing it ,WF gives "status : Error "

I hv seen in WF log , Process has stopped in condition step.

Is there something missed or wrong in condition step ?

I doubt - if my way of declaring element 'Amount' in WF container is ok ?

Do I need to add this field as an attribute in the Bus Obj n then take it in condition editor.

Pls advice how to go about it ??

Best Rgds
