Power Platform Community Forum Thread Details

I have created a powerapp that has an input box for full name. It also has a pen input control. for the onselect of the save to sharepoint button i have this formula: Set(varSignature, JSON(SignatureInputPen.Image, JSONFormat.IgnoreBinaryData)); Set(varSignature, Mid(varSignature, 24, Len(varSignature) - 24)); PenInputToHODSharepoint.Run(varSignature)

This part works perfectly.

I had the flow added to the app and had it configured to make the name of the file that is saved to sharepoint using the current date and time. That worked perfectly. I decided to try and change this part so that the name of the file comes from an input box from the powerapp. Below i have posted the part of the Flow i believe i have wrong and need to fix. I'm not exactly sure i understand how to collect the name from the input box to add as the name of the file in this part of the Flow, can someone help me? The input box name is SigNameInput. I added the .Text thinking it was needed. Is it? When i try and run the flow it fails. Any help appreciated.

"name": "@{concat(parameters('SigNameInput.Text'),'.png')

Hi @SeanTambling

varSignature passed to Flow only contains the JSON object

Create another variable of type string in Flow and then set its value as "Ask in PowerApps"

Then in your PowerApp

Set(varSignature, JSON(SignatureInputPen.Image, JSONFormat.IgnoreBinaryData)); Set(varSignature, Mid(varSignature, 24, Len(varSignature) - 24)); PenInputToHODSharepoint.Run(varSignature, SigNameInput.Text & ".png")

In order for the Flow updates to be reflected in PowerApps, delete the Flow association from PowerApps.

Close the App, Open app in edit mode and then associate the Flow again (sometime the changes in Flow do not reflect in PowerApps due to caching)
