Tkx in advance.

Tkx for the help but still not working.

If I open the browser with the address: http://localhost:xxxx/HelloWorld/Welcome?name=Ricardo&numtimes=3 

It was supposed to write my name 3 times. And i get only 1. Debugging the code I get that it enters the for loop but does not repeat the code 3 times.

Kinda have problems knowing that in debugging (tried add a watch but no do). Doing this:

 <%  For i As Integer = 0 To i > Model.NumTimes %>
     <h3> <%: Model..Message + " - " + Model.NumTimes.tostring %></h3>          
 <%  Next%>

Hello Ricardo - 3

Hi,

As mitja.GTI said, the For-Loop statement is not correct. Please use this code to replace yours.

<%  For i = 0 To Model.NumTimes %>  
<h3> <%: Model.Message %></h3>            
<%   Next  %>

First tkx. This way works perfectly but please help understand this.

Why does this work:

 <%  For i = 0 To Model.NumTimes%>
        <h3> <%: Model.Message%></h3>          
 <%  Next%>

And this not:

 <%  For i As Integer = 0 To i> Model.NumTimes%>
        <h3> <%: Model.Message%></h3>          
 <%  Next%>

Or even this:

 <%  For i As Integer = 0 To i> Model.NumTimes% step 1>
       <h3> <%: Model.Message%></h3>          
 <%  Next i%>

I'm very frustrated with this. I think it's a simple thing but can't get it...

Tkx one more time to all.
