Function not active in formula bar

[Khoward1607]

Hello everyone,

I am fairly new to power BI and I'm sure that the following question is a rookie mistake. Im currently working with Power Bi desktop. My issue is I'm trying to add a calculated column using the function EOMONTH to calculate the last date in the month. The problem is that the function is not being recognized in the formula bar. I also tried it with an IF function, but it's like it's just viewing the function as text rather than a function if that makes any sense?..  I'm not sure if I deselected something to cause the formula bar to not recognize the functions as functions and instead as text. I was able to successfully write an IF function shortly before I started experiencing this issue. I would greatly appreciate some insight on this. Thank you.

@Khoward1607 , You should be able to create a column like

End of month = eomonth([Date],0)

May sure ut column not measure

Thank you for your help. I saved the video you referred me to.  I found that once I completely exited power BI and brought my report backup I was able to type functions once again not sure if it was just a bug?

 Again thank you so much for your time I appreciate your advice.
