OK this is where excel gets frustrating,

I have a spreadsheet with a user form on it and a button that open the form,
the code on the button is

riderinfo.show

works fine

I have another spreadsheet with the same type of setup on it and I get the
error message

Run time error 424

object required

why would one work and not the other


also I want to set the rowsource of a combo box to a spreadsheet called list

so in row source I have typed list!(A2:A4)

and get the error message Could not set the row source property. invalid
property value

some help would be appreciated

thanks
