First-time user, Misc errors when running?

I’ve created an automation, and when I play it I get lots of errors:

Test Sequence.xaml: Compiler error(s) encountered processing expression “array.IndexOf(firstRowValues.ToArray.Cast(of string).ToArray, “Total”)”.
Option Strict On disallows implicit conversions from ‘Integer’ to ‘String’.

Test Sequence.xaml: Compiler error(s) encountered processing expression “convert.ToChar(totalColumnIndex + 65)”.
Option Strict On disallows implicit conversions from ‘String’ to ‘Double’.

Test Sequence.xaml: Compiler error(s) encountered processing expression “totalColumnIndex”.
‘String’ cannot be converted to ‘System.Collections.Generic.IEnumerable(Of Object)’ because ‘Char’ is not derived from ‘Object’, as required for the ‘Out’ generic parameter ‘T’ in ‘Interface IEnumerable(Of Out T)’.

Test Sequence.xaml: Value for a required activity argument ‘Text’ was not supplied.

Does anyone know how to resolve these?
I am using default settings for everything.

Welcome to the community

I believe this is used in assign and the left argument is of type string…please convert that to integer or use .ToString at the end of right expression

Here as well either totalcolumnindex is of type string and you need to convert appropriaely

Here please show the complete implementation…looks liek something required is missing

This error means that the text value for an activity is empty or not provided

cheers
