Rookie Question: How to Get Lat/Long tick marks on map (layout)

[ClaireRose]

Hello All,

Thanks for your willingness to help out.

I've been making maps for quite a while, but have never been able to figure out how to add latitude/longitude tick marks on my final maps. I always have to add that in with another program. I'm sick of it, and I'm sure there's a way to do it, whether I've found it or not.

Do you all have any suggestions?

I've added a map to show the lat/long tick marks I'm talking about.

Thank you,
Claire

p.s. If this was unclear in any way, please let  me know.

I'm going to try that right now.
Thank you so much for your time and expertise, I appreciate it so much more than I can explain.

Thank you so much! That worked and you have saved me so much extra time.
