IF Statements

I'm having problems getting some ASP code to work with a form I'm using. I'm using the script with a multiple page form and want to print a javascript onsubmit value for just one of the forms. I'm getting errors because of the multiple IF statements and I'm not sure how to do this and have the "s show up properly in the output. Can someone tell me how to do this properly?

Code:
<% If step < 5 Then Response.Write " <form action="/script.asp" method="post" name="theForm" id="theForm" & If step < 1 Then Response.Write " onsubmit=""" & "return checkForm(this);" & End If %> & ">" & End If %>
Here is how I want it to output:

<form action="/script.asp" method="post" name="theForm" id="theForm" onsubmit="return checkForm(this);">
