HI, I'm new in the forum and almost new in Power Automate.
I need to compare two dates. One comes from an excel table where the format is dd/MM/yyyy (e.g. 28/06/2022). When reading the table in the flow I set the DateTime format as follows

I set a string variable with this date:

and then setting the condition as follows:

When I run the flow I get the error message:
Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'In function 'formatDateTime', the value provided for date time string 'translationend' was not valid. The datetime string must match ISO 8601 format.'.
What I should do?
