@bhashi

int but again error is coming in add data row

Ok but now it telling you that you have nothing to add data row or your string is empty

dis you imported and edited your in and out arguments well, please check

Hi @bhashi,

Type of ‘i’ should be ‘integer’ and as you ‘Assign’ ‘i=i+1’ before assigning a default value of ‘i’, I think that’s why the error occurs. You can assign a value of ‘i’, i.e., ‘i’ should be declared before assigning.

Thanks & Regards,

@apurba2samanta

You can assign a value of ‘i’ , i.e., ‘i’ should be declared before assigning

This can be done either in the flow or by providing a default value at the declaration of the variable.
