How to plot in geomorph using a csv file

Hi, i need help trying to plot on geomorph using a csv file. i think i need to use arrayspecs or something on those lines, but i get the error messege:

Error in dimnames(specimens) <- *vtmp* :
length of 'dimnames' [3] not equal to array extent

Can someone please help and if theres an easier way to integrate my csv file into geomorph, please tell me.
