Error when using prepData for analysing coordinates (moveHMM package)

[NatalieMay]

Hi I am trying to use the "moveHMM" package for the first time to analyse coordinate data.
the code I am trying to run is:

data <- prepData(Movement,type="LL", coordNames=c("Longditude","Latitude")

but I get an error saying :

x Location 2 doesn't exist.
ℹ There are only 1 column.

and I cannot understand why.
My data set consists of ID, date, Longitude, Latitude and season (2257 obsv and 7 variables)- see bellow for summary. The coordinates have been shortened my R but the data set has them fully entered.

  ID    Date       Longditude Latitude season fseason fID  
  <chr> <chr>           <dbl>    <dbl> <chr>  <fct>   <fct>
1 SM1   2019-05-07       29.4    -29.7 Autumn Autumn  SM1  
2 SM1   2019-05-07       29.4    -29.7 Autumn Autumn  SM1  
3 SM1   2019-05-07       29.4    -29.7 Autumn Autumn  SM1  
4 SM1   2019-05-07       29.4    -29.7 Autumn Autumn  SM1  
5 SM1   2019-05-08       29.4    -29.7 Autumn Autumn  SM1  
6 SM1   2019-05-08       29.4    -29.7 Autumn Autumn  SM1  

please can someone help?
