How do I count visible items in an auto filter?

When using auto filters. Sorting by (1) Date to Date then by (2) Product ID, I show visible rows that I can total the columns (Total Weight) that excludes non visible lines using =SUBTOTAL(9,Q10:Q1000). That Works.

But additionally I need to count ONLY the number of items in the visible column that contain the text of various Truck Companies to get a count of the number of trucks shipped. If I try to count the non blank cells of the visible cells it counts all the hidden cells too.

How do I count just the number of visible cells containing text in a column when in auto filter? OR count someother column containing numbers or text for the purpose of getting a count of the visible lines that would get the same result (number of shipments)?

Which column are we talking about? Assuming column P did you try

=SUBTOTAL(3,P10:P1000)

That should work assuming the "blank" cells are truly blank. If they contain formulas that return a blank then try

=SUMPRODUCT(SUBTOTAL(3,OFFSET(P10,ROW(P10:P1000)-ROW(P10),0)),--(P10:P1000<>""))

Works great. Thank you very much.
