Indicator Species analysis; trouble with multipatt

Hello,

*Error in tx  %*% comb : non-conformable arguments*

Suggestions greatly appreciated.  I am a beginner and this is my first time
posting.

I would like to get the summary for indicator species analysis, using
package indicspecies with multipatt.  I am getting errors, I believe, do to
my data organization.  After reorganizing and reorganizing, nothing has
helped.

data<- read.csv(file="Data1.csv", header=TRUE, row.names=1, sep=",")
ap<-data[c(1:24, 1:81)]
groups<-c(rep(1:4,6))
indval<- multipatt(ap, groups, control = how(nperm=999))
