@Technical_Land problem must be here
can you tell me what are you trying to do let me help you it’s saying that it can’t compare empty string with a number so use pink block this one or you have to set input as number

Maine set karke rakha hai only numbers wo compare Numbers ka hey…
Please use english and also try using pink block instead of blue block
I mean i have already seted to only Numbers and i am not using pink one because the input is number not string value…
