Concat works in Survey123 but not in ArcGIS Online

Niklasg

Hi,

I have written a calculation in my Survey123 under the calculation coloumn looking like this: concat(${ChainageKilometer}, "+", ${ChainageHundred}, ${ChainageTen}, ${ChainageMeter})

It combines the integer questions and adds a "+" between them. The result is written to a text question. In the Survey123 app it works perfectly, and I can send the answer, however in the attributetable when the answer is submitted, the attribute is empty. Any suggestions to what I can change to make it work?

Thank you,

Niklas

Oh so he wants the + in there. I think the web is more picky and will not auto convert int so I would try

concat(string(${ChainageKilometer}), "+", string(${ChainageHundred}), string(${ChainageTen}), string(${ChainageMeter}))

hope that does it

Just checking the obvious: "start koordinat" is a text field, right?

Can you turn on your browser's developer tools and watch the Network tab to see what the actual request is that's being sent?

If you want the first 2 to add then you cannot put the + in quotes that is just text then.

I think you want this. but it would be ugly with all 3 numbers just right next to each other.

concat(${ChainageKilometer} + ${ChainageHundred}, ${ChainageTen}, ${ChainageMeter})

Confused as to what you want now.

I would assume it's for some kind of road-related thing. "Distance along the road" in highway plans is often shown in that sort of format.

Hi guys,

Thanks for your help.

Putting your suggested solution "concat(string(${ChainageKilometer}), "+", string(${ChainageHundred}), string(${ChainageTen}), string(${ChainageMeter}))" into the calculation field did the trick!

Best regards

Niklas
