tempCaseCustomerInfoFormID = Case_Customer_Info_Form[ID != 0].ID sort by Added_Time desc;

//this ID belongs to the row that data lies

// take the relevant.data

tempID = Case_Customer_Info_Form[ID == tempCaseCustomerInfoFormID];

input.Case_ID = tempID.Case_ID;

The code above allows me to bring a Case_ID of another form into this form, on load. I have got a error message saying "invalid value found for the variable Case_ID, Line 5.

How can i remove this error?
