While setting up a dynamic picklist at subform,

I had used  clear row.<subform-field'scolum name> to clear the list

eg:

1. clear row.Area

This would clear the list 

But, now i am unable to save this line of code as it says

Error at line : 1
'Invalid subform Comp Name Area'

Anyone come across a similar error while trying to clear subform's droplist?
