Hello,

Looking for some advice of capturing blank data from an entry form within power apps that is being called upon as a variable within a flow.

So I am using a flow to generate a pdf report. In this example I have an initialize variable called "Project Manager". This variable is then entered into my html that is being converted to pdf. What I need to capture is if the datacardvalue for Project Manager within powerapps is blank then my project manager variable needs to be blank so this will display no value on my pdf.

Currently If no value is entered for project manager. I get an error message of pdf.run failed: The method 'Run' has an invalid value for parameter 'Project Manager'

I have tried NewPDF.Run(If(DataCardValue3.Selected.DisplayName = Blank(),Blank(),DataCardValue3.Selected.DisplayName) but no luck *Datacardvalue3 is my project manager datacard*

thanks,

Jake

I think based on your error message and formula, the flow can't run with a blank value in that parameter. You could consider something like:

NewPDF.Run(IsBlank(DataCardValue3),"N/A",DataCardValue3.Selected.DisplayName)

That might pass a string to your flow, which it might like more than a blank value. Then if you really must, use a Compose action in your flow to convert the "N/A" to blank.

@zmorek thanks so much, the N/A worked. I had to add an If in front of the Isblank. But worked perfectly.
Bad news it appears I will need the value to be blank so I will be needing to go the compose route. I have not done much with composing so I may need a few pointers in this situation.

@zmorek Actually I tried

NewPDF.Run(If(IsBlank(DataCardValue3.Selected.DisplayName)," ",DataCardValue3.Selected.DisplayName)

and this worked for creating the blank space needed. Thanks again for pointing me in the right direction!
