Hi. I’m trying to perform the following comparison

if (params[:bid][:points] \<= session[:user][:points])

But I get the following error

“comparison of String with 0 failed”

I have tried changing the code to this

if (params[:bid][:points].to\_i \<= session[:user][:points])

But now I get  
“too few arguments”

Can anyone see what’s wrong? Surely this should be a pretty simple  
thing?  
Thanks

try a puts on params[:bid][:points] and session[:user][:points] to see  
what it gives, because I guess that one of this 2 vars is nil?!
