Unable to Cast Result with Sum Function

I am trying to increment an item in a list by 1 from a workflow that is kicked off from another list, but when the workflow runs I am getting an "Unable to Cast Result" error.  I see the the return type of Sum() can be either Number or Decimal and the filed I am trying to update is of Decimal type. I have wrapped the sum function in ToDecimal to make sure it is returning what I need and I have also wrapped the 1 in ToDecimal to make sure that I am adding like datatypes.  Has anyone had this issue before?  Below is the trace from the workflow error if it helps.

 

Server stack trace:

Re: Unable to Cast Result with Sum Function

Hello Mike,


 


Along with what Jake is asking for I was wondering if you might be able to provide some more information about the lists you have created? I am trying to reproduce this and the more info we can get about your set up the better.


 


Thanks,


JC
