text in Numbers

Interesting.....I tried several other lines on my form and there is an insertion point on each of them; however, I still cannot get the point on the one that I wanted to change. I'm stopping there and assuming it is just a glitch. Thank you for your help.

Thank you, quinn, for your quick reply. That didn't work. :( I have copied it from an Excel program into Numbers. Could it be that it "froze" everything so that I'm not able to edit? I moved it to Numbers because I'm nervous about upgrading my computer to 64 bit program which won't pay attention to Excel & Word. I have purchased the program Go Office 2019 but I'm still not sure what will happen when I upgrade.
