Urgent Help Needed: How to Fix ESI Challan Upload Error Before Deadline?

Dear sir, I am uploading the ESI challan file, and at that time, we encountered the following error: "Cannot perform '=' operation on System.UInt64 and System.String." Please advise on the solution for this issue. We only have 3 days (15.01.23) left to pay the challan.

Thank you,

K. Anki Reddy

Dear Viswamservices2015-hr, If this happens repeatedly, then check your sheet before uploading to ensure that you have not written any alphabet in the line with the ESIC number. Thank you.
