Hi,
I have two list Excursion Event ( Parent) and List (Child).
I am using a count related look up field on parent to calculate the total no of customers associated with any excursion event. The field name is "No of Customers"
Based on some status field, I am using the SPD workflow to calculate the Valid Customer from the child list and then update it back to the parent list. The field name is "Valid Customers"
Now I want to do some arithmetic on "No of Customers" and "Valid customer" field but seems like count related look up column is neither recognized in workflow nor in the calculated column. Every time I try to read the value of No of customer field, workflow through an error message.
how can I use the count related look up field in the calculations?
Fields on the Parent List:
A=No of Customers (Look Up count related)
B=valid customers (based on flag from the child list)
C =% of Total customers-------> I want to calculate this field based on the above two field --> C= A-B
