Dear Mr Kamlesh.
But,as explained by Mr Lee, the 1st sheet is "NSE" and u're mentioning it to be SimRT...Have u renamed the NSE sheet to SimRT
Secondly, the Cell Name is defind as _ls (by Mr Lee) and u're mentioning _AMI.
I'm a bit confused. Can you please clarify your statement"SimRt!{Ticker}_AMI" interms of the "sheet name" and "Cell Name Definition" as against whats mentioned by Mr Lee.
warm regards...
