Geodist Error

[Nur Jahan]

Hello Statalisters,

I'm facing an issue with the geodist command as in the screenshot below. I don't know what does this error means. Greatly appreciate your help.

I have longitudes and latitudes of two different locations and I would like to create the distance between the nearest of these locations.

geodist is from SSC (FAQ Advice #12). The command expects numerical variables. Try

foreach var of varlist LONGITUDE LATITUDE longitude latitude{
    destring `var', replace
}
geodist LONGITUDE LATITUDE longitude latitude, gen(d)
