如何将贷款提取国家格式校验的消息框改为错误提示？

Got it! To turn that plain message box into a proper error-style prompt, you just need to add the critical error icon and a clear, descriptive title. Here's how to tweak your code:

If txtloanwithcountry = "England" Or txtloanwithcountry = "Wales" Or txtloanwithcountry = "Scotland" Or txtloanwithcountry = "Northern-Ireland" Then
    NumberFormat = "_(£* #,##0.00_);_(£* (#,##0.00);_(£* ""-""??_);_(@_)"
Else
    ' Error-themed message box with critical icon and clear title
    MsgBox "The currency used in the loan withdrawal country must match the number format.", vbCritical, "Currency Format Mismatch Error"
End If

Key improvements made: #

• Added vbCritical as the second argument: This displays a red circular error icon next to your message, making the alert immediately recognizable as an error.
• Added a third argument ("Currency Format Mismatch Error"): Sets a specific title for the message box, so users know exactly what the issue is at a glance.
• Fixed a small typo: Changed "withdrawl" to "withdrawal" for cleaner, more professional wording (optional but nice to have).

This adjusted prompt is far more noticeable and user-friendly than the default plain message box, ensuring users take the mismatch seriously.
