The following are examples of validation equations that can be added to a header within a step in OpenGround Cloud Data Collector

isnumber([HandPenetrometer])

Header	Valid Expression	Message (displayed when Valid Expression returns false)
Sample Base	[DepthBase]>=[DepthTop]	‘Incorrect Depths. Base depth must be greater than or equal to top depth’
Sample Base	[DepthBase]>=0	‘Incorrect base depth. Value must be greater than or equal to 0’
Date Time Sampled	[DateTimeSampled]>[LocationDetails.DateStart]	'Incorrect Date. This location was started on ' + [LocationDetails.DateStart]
Hand Penetrometer	isnumber([HandPenetrometer])	'Value is not numeric. Are you sure this is correct?'
Date Test	[DateTest]<Now()	'Test date cannot be in the future!'
Depth Base	not(isnull([DepthBase]))	'Warning: No depth base has been recorded'
