Returns a value from a table corresponding to a match found in the first row.
HLOOKUP([Value], [TableName], [RowIndex], [MatchType])
Value is the value to be found.
TableName is the table within which the Lookup value is to be found.
RowIndex is the number of the row containing the data to be returned.
MatchType defines whether the match has to be exact (False) or the nearest found (True).
Ensure the data (in the Value field and also in the Table being searched) can be matched.
Spaces and non-printable characters are common causes of data mismatch.
If the function returns a #VALUE! error, a data mismatch could be the cause.
See #VALUE! below for more information.
|HLOOKUP(CarMakeComboBoxReturn, Vehicles, 2, FALSE)||The function looks in the Vehicles table for a match, in the first row of the table, to the value returned from the CarMakeComboBox.
If a match is found, the function then looks down to the second column and returns the value in the same row as the match found.
The rule also specifies that the match needs to be exact (denoted by the FALSE term).
In this case, the Car Make selected in the combo box is "Volkswagen", so the function returns "Golf".

This error often occurs when the value to be found does not exist in the table.
Using the Vehicles Table (above) as the table the value is to be found in, examples of this include:
"Tesla" does not exist in the table.
Modify the table to include the missing value.
"Volkwagon" is spelled incorrectly and does not exist in the table.
Similarly the entry in the table could have the incorrect spelling.
Ensure spellings are correct in the value filed and table values.
"Ford " has a space at the end, where the table value does not.
Similarly the entry in the table could have the extra space.
Ensure trailing spaces are removed.
Consider using the Trim function to remove whitespace characters.
The Trim functions will also remove additional spaces in between words.
Finding and cleaning offending characters using a third party editor is recommended.
Notepad++ allows all characters to be shown.
Paste the data into Notepad++ and select View>Show Symbol>Show All Characters
Remove all non printable characters and copy the data back into DriveWorks.
