Humidifier not Working [closed]

I am trying to humidify the air in my building, as around 20% of the time humidity is below 30%.

I think I have followed the indications of this post fully (https://unmethours.com/question/26822...), but my simulation fails at the start. When I check the ERR file, the following error message pops up:

* Severe * Humidifiers: Missing humidity setpoint for Humidifier:Steam:Electric = ELECTRIC HUMIDIFIER

* ~~~ * use a Setpoint Manager with Control Variable = "MinimumHumidityRatio" to establish a setpoint at the humidifier outlet node.

* ~~~ * expecting it on Node="NODE 136".

* Fatal * Previous severe set point errors cause program termination

I find this odd, as I have done the following things suggested by the post:

Include a minimum and maximum humidity schedule (Schedule Type: Percent) into my thermal zone in the HVAC Systems tab
Add a SetpointManager:SingleZone:Humidity:Minimum and associate it to the thermal zone
Add a Humdifier:Steam:Electric into the HVAC loop in the location suggested in the post

I have alternatively tried to use a SetpointManager:MultiZone:Humidity:Minimum as I can set a minimum humidity ratio, but I get the exact same error.

Is the SetpointManager:MultiZone:Humidity:Minimum at NODE 136 as the .err suggets? This node should be the one after the humidifier

@Alejandro Lopez what simulation tool are you using? From your error messages, it looks like EnergyPlus, but you could be using an interface like DesignBuilder or OpenStudio. Please add a tag for the simulation tool to your post so that others know how to provide better help.
