您好Alexandre，

Hi Alexandre,

您使用的是SharePoint Online吗？

Are you using SharePoint Online?

我尝试在SharePoint Online列表上使用PowerApps自定义列表表单，在发布到SharePoint后，当我创建新项目时，我可以通过Attachment字段附加多个文件，如下所示：

I tried to customize list form using PowerApps on a SharePoint Online list, after publishing to SharePoint, when I created a new item, I could attach multiple files via Attachment field, like the below:

保存后，它也保存得很好。

After saving, it also saved well.

您是否更改了PowerApps中的附件字段？

Did you change the attachments field in PowerApps?

请创建新列表并通过PowerApps进行自定义，比较结果。

Please create a new list and customize it via PowerApps, compare the result.

谢谢，

Wendy
