I have an action that as existing outputs. An example of one of them is
Process Using: [XPath] /my:myFields/my:supervisorCheck Return results as: [x]Text Inner XML Outer XML Store result in: [sSupervisorSignOff]
I see that sSupervisorSignOff is a Workflow Variable, so I have created a variable called sOshaRecordable with the type of Yes/No. The default value is No, and "Show on start form" is unchecked (just like all the other variables).
The problem that I am running into is that when I create the new output in the action
Process Using: [XPath] /my:myFields/my:OshaRecordable Return results as: [x]Text Inner XML Outer XML Store result in: 
the "Store Result In" field lists all the other variables except sOshaRecordable.
I have read the help documentation which just says
Store result in Use the drop-down to specify where the resulting text should be stored. More than one output value may be entered. To specify additional output select Add output and fill in the required information.
I have looked everywhere on Google, and I can't figure out why this variable is not showing up. So, I come to you lovely people seeking wisdom.
What am I missing? How do I fix this?
