Check if string its empty

Hello I have a barcode scanner that scans a qr code. Then it extracts some values. 

I then have a label that holds the value. I want to make a function that says "If the field its empty assign variable1 if the fields its not empty do First(Match(BarcodeScanner1.Value;"FORSIKRING:(.+)";Contains).SubMatches).Value)

How can i perform this ? I tried with If(IsBlank(Label2.Text);"variable1";First(Match(BarcodeScanner1.Value;"FORSIKRING:(.+)";Contains).SubMatches).Value)


But it gives error


Hmm its close, but only god "variable1" each time now :S

Hi @langsem ,


You could try this code:

If(IsBlank(Trim(First(Match(BarcodeScanner1.Value;"FORSIKRING:(.+)";Contains).SubMatches).Value))),"variable 1",First(Match(BarcodeScanner1.Value;"FORSIKRING:(.+)";Contains).SubMatches).Value))

// Trim function can delete all spaces in a text string, except for a single space between words.


Best Regards,


THank you so much for help !! YOu rock!
