HubDB multiple listing of else information


Hello community Smiley Happy

Perhaps somebody can help me… I have got a problem with my else condition:

At the end, I get multiple error message: "Keine Veranstaltung…"

How do I have to modify the code to see my created error message just once.
I tried to put the if and else condition above the table row definition, but then nothing happens…


Hi @patrickhummel,

The reason that error message is printing multiple times is because it appears in the for loop. The code within the loop will execute once for each row in table, so that error will be printed once each time that if statement fails. To only print it once, you’d need it to appear outside of the for loop.
