Can someone help me to solve this compile error
Your Indexval is a generic value, that may have a different value as well which can not be converted as double sometimes. Better go with TryParse then convert it as double.
It’s solved. Thank you guys.

" Convert.ToDouble(string)" function does not work.
You can use the code below;
