Help needed with this statement. Filter with !IsBlank.

[stapes]

In this example, if the collection has no quantities outstanding (Qty-OS) and all rows have a PDN number (a value that looks like "PDN123456", I want to disable a button.

This is my code behind the DisplayMode property:

If(
    gblPdnLock = true || (CountRows(
        Filter(
            colControlSheet,
            QtyOS = 0
        )
    ) = CountRows(colControlSheet) && CountRows(
        Filter(
            colControlSheet,
            !!IsBlank('PDN-No')
        )
    ) = CountRows(colControlSheet) && CountRows(
        Filter(
            colControlSheet,
            StartsWith('PDN-No',"PDN")
        )
    ) = CountRows(colControlSheet)),
    DisplayMode.Disabled,
    DisplayMode.Edit
)

This bit is returning a 0 and it should be a 1. There is a row with a non-blank value.

CountRows(
        Filter(
            colControlSheet,
            !!IsBlank('PDN-No')
        )

Obviously, this statement is not coded correctly.

Can anybody help?

Try removing the extra ! in front of Is Blank

Thanks @JR-BejeweledOne  - I actually solved this problem moments after posting. Unfortunately there is no method of deleting my question.

This was the solution:

CountRows(
        Filter(
            colControlSheet,
            'PDN-No' <> ""
        )
