No record found within criteria

No record found within criteria

hello,

I'm looking up records in a form. Is there an expected response from the system if there are no record found?

Here's my code:

// Check to see if there are any batteries that need to be replaced.
            Battery  =  System_Batterys  [ID = TempAssignedSites]; (TempAssignedSites is the record ID to look for)
            if (Battery.Battery_Replacement_Date  <=  zoho.currentdate.addDay(120))
                  {
               
                  // If the batterys meet the criteria tell the user to replace the batterys.                 
                        BatteryReplace = "Replace Batterys";
                 
                  }
            else if (Battery.Battery_Replacement_Date  >  zoho.currentdate.addDay(120))
                  {
                       // If the battery date is beyond the criteria, tell the user the batterys are OK.
                        BatteryReplace = "Batterys OK";
                  }

 >>QUESTION<<
>>            else if there is no record found
>>                  {
>>                        BatteryReplace = "No Battery Data";
>>                  }


The above code works well... but what if there is no record in [System_Batterys] for the search ID?
On the condition "No record" I'd like to tell the user --> "No Battery Data Found".
