Use of IF, Then, Else IF Statements to Control Screen Fields

Zones: Scripting Languages, JavaScript, Active Server Pages (ASP)

Tags: JavaScript and ASP, IE 6

I am workng on a website for work and need to make a page show only one input field if it meets a certain criteria. The site is ASP and javasript was initially used for the input fileds and buttons.

When a user clicks on the button with value=<%=b_title> two fileds appears showing one input field that divides and rounds the number once they click on the "Calculate" button. Then it trasnfers that number into a readonly field. When the user feels everything looks correct then they will click on the post button or cancel to start over again.

What i need to happen is if the fiield, <%=rslic.rows(0)("catdesc1")%> contains the word ski, then only have an input field show with a post button.
