I'm having trouble with a null value.
I have the variable vMaxFechaTrafico that evaluates to null.
When I run the code I get this error.
If I replace the variable with a dummy one defined as LET vPrueba = Null(); it works fine.
I can't find what's wrong with vMaxFechaTrafico.
I would appreciate any light you can shed on this.
Go to Solution.
You could just use IsNull( vMaxFechaTrafico ) as there is no need to $ substitute in that function.
Replaced by Not '$(vMaxFechaTrafico)' = '' and worked!
