If Function with Lookup

[MaxWendorff]

Hi, I am making an app that scans barcodes and uploads the data to a sharepoint list. Everyday a new pick list is going to be uploaded so only data thats on that list can be scanned. I have a funtion right now that using lookup that references the list and does not display the data if it is not on the list. I want to add an if statement to that funtion so that if the data is not on the list then the app displays an error. My current code is:

If(LookUp(Table2_1,Location = BarcodeScanner1.Value), BarcodeScanner1.Value, "Error")

I have tried a lot and can not seem to get te syntax down for the IF funtion. 

Any Help would be greatly appreciated!

Try this:

If(IsBlank(LookUp(Table2_1,Location = BarcodeScanner1.Value, BarcodeScanner1.Value), "Error")

#Basically you checking if the result is blank. if it is show "Error". If your result produces a value like 0 you might want to remove "Isblank" and do something like:

If(LookUp(Table2_1,Location = BarcodeScanner1.Value, BarcodeScanner1.Value)=0, "Error")

Thank you so much for your fast response!

I tried the funtion and I received this error:

"Unexpected charecters, the formula contains 'Paren Close where Eof is expected."

Is this just a syntax issue?

my bad

if you using this one : If(IsBlank(LookUp(Table2_1,Location = BarcodeScanner1.Value, BarcodeScanner1.Value)), "Error")

I missed a bracket before ","Error" - try the formula above.
