Hi,

How do I disable a node if the parameter linked to it is left null ?

I know about "equal-to" and "not-Equal-to" but how do I use NULL/NOTNULL ?

Thanks

Hi,

You can check to see if a parameter has been set using the {{?<ParameterName>?}} syntax - this will return true if the parameter has been set, and false otherwise.

Therefore, to check if a parameter "MyParam" has been set to some value, you could use {{?MyParam?}}.

If you wanted to disable the node if the parameter has not been set, you could set the Enabled parameter to:
{{?MyParam?}}


Hope this helps,
Tim.
