@cool_babe,

You are trying to replace something where the source not containing anything.

Hello @cool_babe

You can get this error if a variable is not initialised properly or if doesn’t hold any value.

Print those variables in a console and check whether any value is there.

Thanks

The variable is not initialized properly @cool_babe

Can you print the variable and check it. Do you received any value.

Hi @cool_babe
This is initialization error

If u create a array,list, datatable like any variables u need to initialization before u store the data into the variable
Like
Array->new string(){}
List_string->new list (of string)
Dictionary(string,int)-> new dictionary (of string,int)
Datatable-> new system.Data.Datatable

Thanks
