Thank you
In your assign activity, one of the variables are not initalised. Please check.
Hi @mcLauge
Welcome to UiPath community buddy
Kindly check with the variables in the right side of the assign activity, as it might not have any values in it and this error occurs only because of that
you are almost done
Kindy check that and get back for any queries or clarification
Cheers @mcLauge
Hello @mcLauge
welcome to our community
Before save the result in forth column.check all other three column have value or not.
Thanks
One of the instances is probably null, try putting some random values to the first 3 columns before the Assign activity to check this.
I want to take the value from each cell in the excel file, so I canβt take a fixed value.
What VB expression should I use?
Fine lets do one thing
lets check with the value of the CValue, DValue, EValue and FValue
βuse a write line activity and mention them like thi
CValue.ToString+ββ+DValue.ToString+ββ+EValue.ToString+β_β+FValue.ToString
and lets check whether any value is getting displayed in the output panel, share that screenshot as well buddy
if the values are getting displayed we are good enough
or if the values are not getting displayed its clear cut that this issue is because of those null values
βand if there are null values we need to check with the way the excel file is read and stored and need to check what is the source of these variables in your workflow
Kindly try this and let know for any queries or clarification
