## What it does
**VBA Code Description**
=========================

### Purpose
This VBA code is designed to handle the loading of a specific form in an Access database. It checks for the presence of a mandatory field (`PartNumber`) and provides error handling if it's missing.

### Detailed Explanation
#### 1. Option Compare Database
The first line, `Option Compare Database`, specifies that string comparisons should be performed according to the database collation order. This is an important consideration when working with data in Access databases.

#### 2. Form_Load Subroutine
The `Form_Load` subroutine is a standard event handler in VBA that gets triggered when a form loads.

#### 3. Error Handling and Mandatory Field Check
Inside the `Form_Load` subroutine, there are two main sections:

    *   **Error Handling:** The `On Error GoTo die` statement specifies that if an error occurs during the execution of the code within this subroutine, it should be caught and handled using the `die:` label. This prevents the program from crashing.
    *   **Mandatory Field Check:** The following lines check if the value in the `PartNumber` field (represented by `Me![PartNumber]`) is null or empty (`IsNull(Me![PartNumber])`). If it is, the subroutine executes the code within the `End If` block, effectively ending the subroutine and preventing any further execution.

#### 4. Selecting and Closing a Form
The following lines of code are used to select and close another form in the database:

    *   `DoCmd.SelectObject A_FORM, "DS CNC"`: This line selects an object (in this case, a form named "DS CNC") using the `DoCmd` object.
    *   `DoCmd.Close`: After selecting the other form, this line closes the selected form.

#### 5. Error Handling Catch
The final label (`die:`) serves as a catch-all for any unhandled errors that may occur during the execution of the code within the `Form_Load` subroutine. When an error is encountered and it's not caught by the previous `On Error GoTo die` statement, the program jumps to this label, allowing it to continue running while still providing some level of error management.

**In Summary**
This VBA code ensures that a specific form loads properly in an Access database by checking for the presence of a mandatory field (`PartNumber`). If the field is missing, it triggers an error and tries to load another form in an attempt to mitigate any issues.
