Hi Guys, 

I am a newbie and I am trying to automate document numbering based on user input from a dropdown or lookup input. For now, I used a long dropdown list and was following some youtube videos to create this code. 

The code seems to work, but it keeps running and doesn't stop.

It is a single form with two fields, the type of journey and the document code, based on the journey made, it will create a corresponding code. Now there can be many journey types and I was each to have a unique code that accumulates. 

Below is the code: 

LastJourney = Cargo_Manifest[Journey == input.Journey] sort by Added_Time DESC;

if(input.Journey == "BI-TIL")

{

input.Journey = "BI-TIL";

}

else if(input.Journey == "BI-NGY")

{

input.Journey = "BI-NGY";

}

else if(input.Journey == "BI-BCV")

{

input.Journey = "BI-BCV";

}

else if(input.Journey == "BI-VND")

{

input.Journey = "BI-VND";

}

else if(input.Journey == "BI-ELS")

{

input.Journey = "BI-ELS";

}

else

{

input.Journey = "BI-TCZ";

}

if(LastJourney.count(Manifest_Code) > 0)

{

getlstnmb = LastJourney.Manifest_Code.getsuffix("-");

getnumber = getlstnmb.getsuffix("-");

newNumber = getnumber.toNumber() + 1;

input.Manifest_Code = input.Journey + "-" + newNumber;

}

else

{

input.Manifest_Code = input.Journey + "-" + 1;

}

Thanks a lot for any help and sorry for any bother. 

thanks 

Richard
