@rahul_521, maybe you will need to use .<=${__005} instead of <=${__005}.

I floated the form without that validation. However the problem remained as same even after applying your solution. Moreover the condition is not getting saved. When I reopen the setting of the question it get vanished

@rahul_521, if this is the case, I would advise you to validate your XLSForm through this online validator to see if you should be able to identify the syntax issues present within your XLSForm.
