A stage block connection problem

I have defined biological and sedimentation tanks as A Stage.
However, connections with other blocks cannot be established.
The attached warning image is attached.

Thanks in advance for your help.

Hi,
difficult to give you a clear answer ...
The error message is clear: the cardinality (i.e. nr of elements in a vector) of the two terminals you are trying to connect does not match.
Which makes me think there's an incompatibility between the underlying models. This should not be the case for 'regular' ASM models.
Which instance are you using?
And which models are you connecting?

Hi,
When we try to establish model, we are taking error message like in the attachment. We have changed instance also but we took error message again. What do you think about solving of this situation.
Your sincerly.

That error message should definitely not occur if you are using ASM1Temp.
Are you perhaps modifying a sample / tutorial / template ?

Try and delete the output block; and place a new one. Then reconnect the clarifier and the pipe.
