Hi AmitLoh,
What are the column types?
I guess there might be some column types that are not supported in the filter function.
Please try to enter Formula1 [,Formula2,…] one by one to see which one is invalid.
Filter( Table, Formula1 [, Formula2, ... ] )
I tried with the similar filter function on my side, it can filter with no error. I set the Items property of the Gallery looks like below:
Filter(Sort(listF,ID,Ascending),(Title=TextSearchBox1.Text || q7kf=TextSearchBox1.Text ||g87p=TextSearchBox1.Text))
Best regards,
Mabel Mao
