I have a search page (hidden link) built with Toolset with a filter search that shows some products. I have added the following code in order to list the results number:
Hello. Thank you for contacting the Toolset support.
Assuming that you are using Toolset Block - what if you try to add the conditional block and add the "Result" and "Results" word accordingly when there is one result display "Result" and when more than one display "Results".
Where as you can see under the "How-To Steps" section - you should compare the condition to if number of items found by view equal to 1 you should display "Result". Add another conditional block and compare the condition to if number of items found by view greater than 1 then display "Results".
I hope the solution shared above will help you to resolve your issue.
