Hello,

We have a repeating grid of source section. We have a property pxcoveredcountopen to fetch count of all open child cases. We have section in assign-work list class and RD in work class. we have used join named W to join assign work list and work class. We are able to successfully populate the pxcoveredcountopen column in the section without any issus. 

Now we have an enhancement to make the pxcoveredcountopen value to show up only when the pxcoveredcountopen is greater than 0. we have added that condiiton in visibility as expression and its throwing an error. 

Can you help resolve this isse? how come we are able to use this in propoerty but not in visibility condition.

Attached are the images.
