Hi,

I’m trying to use the Send Email node conditionally. I want the Send Email node to execute if a field in my workflow has the value of 1.

if value = 1 Then run Send Email  
Else stop execution

Hi @lavvanr,

That’s what [IF Switch](https://nodepit.com/node/org.knime.base.node.switches.manualif.ManualIfNodeFactory) node does.

Use a [Table Row to Variable](https://nodepit.com/node/org.knime.base.node.flowvariable.tablerowtovariable.TableToVariableNodeFactory) node to convert the “value” to flow variable then a [Rule Engine Variable](https://nodepit.com/node/org.knime.base.node.rules.engine.RuleEngineVariableNodeFactory) node to create a new variable based on the value which would be “top” if value = 1 and “bottom” if value is not 1 then use this variable to select the port in IF Switch node.

😊

Or easier, use table row to variable followed by the `If switch(Flow variable value)` node in the Vernalis contribution
