Validating a Barcode using part of the Output String

[Skitzer1985]

Hi,

Hoping someone can point me in the right direction. My current job is creating a Work Tracking system, using QR codes to track jobs, but once in a while we will get a false scan using the barcode scanner feature. I was wondering if anyone could point me in the direction on how, using the first part of the QR string, Check if 3 letters are there to proceed with the scan. I thought maybe a 

If(Left(BarcodeScanner1.Value,3,"Value",
Set(
variable,
Patch(

and so forth for my patch to Sharepoint.

Any help would be greatly appreciated.

Hi @Skitzer1985 ,

Are you trying to confirm the first three characters are letters (not numbers)

With(
   {wAlpha:Left(BarcodeScanner1.Value,3)},
   If(
      Value(First(wAlpha) = 0 &&
      Value(Last(wAlpha) = 0 &&
      Value(Last(FirstN(wAlpha,2)) = 0,
      Set(
         variable,
         Patch( 
         . . . .
         )
      )
   )
)

Hi @WarrenBelz ,

Thanks for the quick response, I was able to do the Validation of the QR using this:

//Write Recorded Data Back to Sharepoint
//Top Line authenticates that the first 3 Letters Match String (ASM) to ensure the tag is correct
If(
    Left(
        VarScan,
        3
    ) = "ASM",
    ( 
//If ASM tag is present, Will create Record in Sharepoint
 Set(
        varRecord,
        Patch(

By the way, thanks for your help on other posts, it's help immensely

Hi @Skitzer1985 ,

If you had told me the value had to be "ASM" rather than Check if 3 letters are there, my response would have been pretty much what you have  . . .
