i want to add lat long locations to map. I tried importing a .txt file with coordinates. what format do the coordinates need to be in? 42 31 31.334, -77 32 45.32 was what i tried

Decimal Degrees - 42.5, -77.5 etc

It shouldn't struggle as long as it gets parsed as numeric instead of strings.

you currently have this 42 31 31.334 which is degrees minutes and seconds, you need to convert them to decimal degrees...written out syntactically

42 31 31.334 = 42. 31.522233333 degrees decimal minutes = 42.525370555 decimal degrees

degrees remains, then take seconds and divide by 60...add that to minutes...divide that by 60 and that is the decimal portion of the term

You need actual numeric xy coordinates in geographic ("decimal degrees") or projected (e.g. "meters") to plot them on a map.

Fortunately, if you name the field names exactly right, those locations can be converted on the fly for you. There's also a tool available that can convert those text strings to geographic (decimal degrees).

The skinny is here in the ArcGIS help (this applies to 10.1/10.2):

Adding an ASCII or text file table > How coordinate information is determined

After convering to decimal degrees, I tried the command “add layer from file” with the .txt file and got the errror below

X is longitude (-77ish) Y is latitude (42ish) Make sure that you have a comma-delimited field name and no blank lines in the data

From what application - Portal, ESRI Desktop (ArcMap) ?

Try saving file as a csv file.
