Hello Team,
Good Day!
I have a customized Power Apps, i have created a duplicate detection for two Datacards. 1. Document number and 2. Check Number. I used lookup formula when the Datacard is saved. On select option for the submit button the below formula used but it is showing a warning message. If(IsBlank(LookUp('Europe Manual Check Request',DataCardValue18.Text = 'Document number', LookUp('Europe Manual Check Request',DataCardValue11.Text = 'Check number')), SubmitForm(SharePointForm1), Set(showDialogue,true)))
Pls help me. Refer screenshot below -
