Hi,

I am creating a form that is a log of keys going in and out, I have set up the start of the form and have it linked to my Data Source (sharepoint list)

This is my form:

As you can see i have already linked the Pen Input to the Attachment using this formula.

Table({
DisplayName: Concatenate(
"image",
Text(
Now(),
"[$-en-US]yyyy-mm-dd-hh-mm-ss"
),
".jpg"

),
Value: PenInput1.Image,
AbsoluteUri: "",
Id: "00000000-0000-0000-0000-000000000000"

})

What i would like to do is after i submit the form and go back into it to change the status to out i will be able to create a new signature and it be saved as a separate attachment.

At the moment every time i put a new signature into the pen Input it overrides the current attachment.

Any help would be appreciated.

Hi @JEVANSAP ,

Please try this formula on items of attachment control:

Ungroup( Table({Value:ThisItem.Attachments},{Value:Table({ DisplayName: Concatenate( "image", Text( Now(), "[$-en-US]yyyy-mm-dd-hh-mm-ss" ), ".jpg" ), Value: PenInput1.Image, AbsoluteUri: "", Id: "00000000-0000-0000-0000-000000000000" })}),"Value")

It will not overwrite the attachments uploaded before.

Best Regards,

Thank you, this has worked how i was hoping, the only thing is that when i create a new item through the app it has a blank attachment which i have to click the x button to get out of it. I have also now added a max attachment value into the properties which means it wont keep adding more attachments as i go into it.

This image shows the blank attachment:

Kind Regards

Justin
