Flagging an error if variable name does not match

[#1]

Hi all,

I want to build a simple error trap where it will flag the error if the variable name from the user defined variable name with the existing table variable name. For example as below;

User defined Data table

Variable Name

1. Benzene

2. Methane

3. Ethane 

Existing Data Table

Variable Name

1. Benzene

2. Methane

3. Ethane 

4. Propane

5. Pentane

6. Hexane

I tried to used !contains function, but it seemed that I dont use the syntax properly. I'm a very new to jmp script, so I'm seeking for anyone in the community help

Inputdt = User Defined Data Table Name
mvdt = Existing Data Table Name

//Get required variable lists from user define Data Table

varListInput = Column( Inputdt, "Variable Name" ) << get values;

// Error trap - if # UserDefinedTable & # Existing Data Table variables don't match, then break code & output error message. 
//Obtain column names from existing Data Table from list
colnames = mvdt << get column names( string );

show(colnames);
show(varListInput);

If(!contains Item ("colnames", "varListInput"),
	Message = Dialog( "The Variable Name does not match with Existing Data Table.Please correct your Input Table." );
	Stop();
);

The Contains Items() function requires the data to be in Associative Arrays.  If your items are in lists, the below method will work.

Inputdt = User Defined Data Table Name
mvdt = Existing Data Table Name;

//Get required variable lists from user define Data Table

varListInput = Column( Inputdt, "Variable Name" ) << get values;

// Error trap - if # UserDefinedTable & # Existing Data Table variables don't match, then break code & output error message. 
//Obtain column names from existing Data Table from list
colnames = mvdt << get column names( string );

show(colnames);
show(varListInput);

For( i = 1, i <= N Items( varListInput ), i++,
	If( !Contains( colnames, varListInput[i] ),
		Message = Dialog(
			"The Variable Name does not match with Existing Data Table.Please correct your Input Table."
		);
		Stop();
	)
);

Thank you, it is working fine now
