this is my first try on shiny , could you please help me? this is the code:

server <- function(input, output) {

  output$EPV <- renderText({
    
    
    #Reading Data
    AM92= read.csv("AM92Table.csv",header = TRUE,sep=',')
      
        
    #Calculate kpx 
    
    KPX=function(k){
    
      kpx=1
      
      for (i in seq(0:k-1)){
        
        px= 1-(AM92$qx[input$Age-17+3+i])
        kpx=kpx*px
      }
      return(kpx)
      
    }
      
    #whole Life Annuity Due   
    
    ax=1
    
      for (j in seq(1:(120-input$Age))){
        
       a=(1+input$interest)^-j*KPX(j)
       ax=ax+a

    }
    
    Annuity=input$Amount*ax })
}
