Hi. 

I have tried using triggers in "When an item is created or modified". Trigger for specific value in column worked OK:

@equals(triggerOutputs()?['body/Planned_x0020_delivery_x0020_dat'],'Planned delivery date exceeded and data not delivered')

I also want to trigger flow when value in column changes from "Planned delivery date exceeded and data not delivered" to blank (NULL). I have added additional trigger but it is not working and moreover first one also stopped working:

@isblank(triggerOutputs()?['body/Planned_x0020_delivery_x0020_dat'])

Have you used the <'> for column name?

@not(isblank(triggerbody?['ColumnName']))

or try

@equal(triggerbody?['ColumnName'],'Null')

@RezaDorrani , is there any documentation of what expressions are supported in trigger conditions? I'm using the SharePoint - item is created or modified trigger and want it to only run when a particular column (which is a lookup column in the list) has a value (any value, not a specific value). 

Using the condition @not(isblank(triggerbody?[ColumnName])), I'm getting this error:
