# DMin

## Using the DMIN Function

In this tutorial you will learn how to use the DMIN Function.

Take an example Table of Customers.

CustomerT

2JoeSmith716555343401/03/19905005True

14PezzDispo26/09/201204True
16BobSmith04/10/201209True

In this example we will find what the minimum number of days grace any of our Customers have. Like the DMax or some of the Domain Functions we don't need a Criteria.

The DMIN function returns a value from a specified set of records (or domain) containing the minimum value.

=DMIN(Field, Domain, Criteria)

Query

The results using a Query would be

```	SELECT DISTINCT TOP 1 DaysGrace FROM CustomerT ORDER BY DaysGrace
```
tblNames

1RichardRost716555777701/01/201210011True
10BarbraPeters829282728831/12/2005501True

FORM

In a Form you could set the Default Value of a Textbox to

```	=DMIN("DaysGrace", "CustomerT", )
```
VBA

In a Form add a TEXTBOX control and rename it "txtDMin", then you could add the following in the Load Event.

```	Private Sub Form_Load()
txtDMin = DMin("DaysGrace", "CustomerT", )
End Sub
```
