Hi everyone,

I meet a problem with “read range” activity, the error info is “Read Range: Object reference not set to an instance of an object.”, but the error will disappear when I modify the format of column ‘A’ to “number” and save. You can see the details form the following picture, could you help me with this? Thank you very much!

Hi @yu.xingxing

This error occurs when the variable we are passing is empty, please put the message box before read range activity and see if all the variables have values.

Thanks to
