The following table contains some example Hide If statements that can be used for Headers in OpenGround Data Collector

Header	Expression	Result
Sample Diameter	[Type] <>'U'	Only show diameter if the type is U
Sample Base	in ([Type] ,'U', 'P')	Hide the base depth if the sample type is U or P
Sample Diameter	isnull([Type])	Hide sample diameter if there is no Type defined
Sample Diameter	not in([Type], 'U', 'UF', 'TW','TWF','P','PF','U/38')	Show the diameter if the Type is U, UF, TW, TWF, P PF or U/38.  Note the use of NOT turns the expression from a “hide if” into a “show if”
Sample Diameter	isnull([Type]) or not in([Type], 'U', 'UF', 'TW','TWF','P','PF','U/38')	Combine the last two – Show if the Type is U, UF, TW, TWF, P PF or U/38 and don’t show if there is nothing defined. Note: Make sure the isnull() condition is the first condition (known issue).
