Previous script logic no longer works with new application builder

Previous script logic no longer works with new application builder

All,
in the old system the following code would ignore fields that had nothing selected, and would only perform the INSERT command for fields that had item selected in the dynamic pick-list.

1. // If the serial number field is set to something other than -Select- then data will be inserted into the data capture form. else will be ignored.
   if(input.Serial_Number_One  !=  "-Select-")
   {
   
   
2.     insert into Crossover_Testing
       [
        Added_User = zoho.loginuser
   
   
3. etc...........................
   

this statement is no longer functional. I receive an error stating that the dynamic pick-list list is now a BIGINT,and the -Select- is not compatible. ZOHO acknowledges this is now by design, however I cannot find a fix for this issue. I was told they would email me a code snippet to fix the issue, however waiting for them is an entire other issue.

So frustrated with ZOHO support at the moment, I am considering moving everything to a new provider. grrrrrrr

Thank you in advance to anyone who may be able to help, site is currently down until I find a solution.
