I resolved this. Thank you.

@Anum If you resolved it, then please post what the problem was and how you fixed it.
For reference:

can you tell me how, because I am facing the same problem

Go to admin and change the data type of the attribute as category

still the same problem

i don't know where the problem

@Mohamed011 Please read this:
Field Filters should not have column or operator, just the variable.
And you cannot use table aliases.

You cannot use table aliases as @flamber said. You need to do this
where company={{company}}

@Anum No, if you are using Field Filters, then you should not have column or operator.
It should be:
where {{company}}
Please just read


thanks for all it is working for me now.
I have another question, if I want to create a mathematics operation based on the results of two questions for example calculate the sum of one column in a table and the sum of another table, then calculate the percentage between them. how can i do that

@Mohamed011 Please create new forum topics, so it doesn't end up with one huge topic spanning many different questions/problems.
