CountX with string does not contain "."

Hi all,

Bit of a newbie question here, Im trying to filter rows in the table where a row does not have a "." suffix on the end.

For example the table name "Table 1" with the Column name called "ElementID". Data type for ElementId is a string.

If we consider a dataset below:

ElementID

dddd.1111

gggg.3535

ggg

hhrt.agb

hhh

hogif.1345

I want a function that just returns the rows that do not have a  ".suffix", in this instance "ggg" and "hhh". I'd like to count these rows and put it in a card visualisation.

I've managed to get all the count of all the rows as below:

count = COUNT('Table 1'[ElementID])

I've done some research on the containsstring function and CountX function, but i'm struggling to put them all in one function. Please see my attempt below. I know the containsstring function returns a bool but thats the extent of my knowledge.

count = COUNTX(FILTER(NOT(CONTAINSSTRING('Table 1' [ElementID], ".")

Any suggestions would be greatly appreciated.

Thanks in advance
