I posted an updated version that handles IsNull a little better. I tested you equation you sent me and it works if you remove the YEAR() part. A IIF statement in VB evaluated both true and false parts, so you cannot pass a null in and define a process on it.

You cannot set a non string field to an empty string. Even an empty string is a string. If you are trying to set a value as null, I am not sure you can. We would need to translate a value you entered as null to a true null value. Would you want use to translate <Null> to null?

Can you download the beta and try that? I fixed a bug that might be the cause of your issue.

After we translate the fields to values, we pass the expression to the MSScriptControl.ScriptControlClass object. I think you want to us the isNull expression, so like below: IIF(isNull([FIELD]),TrueValue,FalseValue)

You will need to generate the main lines off some point of reference. If you can locate the valves, then draw the mains from valve to valve following the road ways, other than that, I am not really sure. Once you have the mains, there are automated tools to connect meters and hydrants to the mains through laterals.

Sounds like a permission issue to the registry to me. Either the key preloadVBA does not exist or you do not have permissions to change it. Please try getting administrator rights to your machine and try the install. Also, what version of ArcGIS do you have installed? I am going to move your post to the ArcHydro forum, they are best suited to help you out with Hec GeoHMS.
