Hi @Anonymous ,
Could you share more details with your issue?
1. What is the usage of parameter?
2. What is the formulas you used to count the gallery item? CountRows(Gallery1.AllItems)?
I have made a test based on your description, but don't have the issue your mentioned.
In my test, I use the passed parameter to filter the gallery, and use countrows function to count the gallery items.
No parameter
with a patameter
Also you can follow my test to check if your issue still remains.
Best regards,
Sik
