Hi,
I'm new to asp so could someone help me with this variable. I would like an user to enter a number 1-6 into "fname" and click submit and for the page to return a picture with the varible in the source.

I.E.
<img src=&quot;/images/Map/loc&quot;& (&quot;fnum&quot;) &&quot;.gif&quot;>

here is my code
++++++++++++++++++++++++++++++++++++++++++++++
<html>
<body>

<form action=&quot;demo_mapping.asp&quot; method=&quot;get&quot;>
Please enter the number 1-6:
<input type=&quot;text&quot; name=&quot;fnum&quot;><br><br>
<input type=&quot;submit&quot; value=&quot;Submit&quot;>
</form>

<%
If Request.QueryString(&quot;fnum&quot;)<>&quot;&quot; Then
Response.Write (&quot;the number you chose was &quot; & Request.QueryString(&quot;fnum&quot;) & &quot;!&quot;)
End If

%>
<img src=&quot;/images/Map/loc4.gif&quot;>
</body>
</html>

Thanks a bunch

Something like this? I didn't try it though.



<html>
<body>

<form action=&quot;demo_mapping.asp&quot; method=&quot;Post&quot;>
Please enter the number 1-6:
<input type=&quot;text&quot; name=&quot;fnum&quot;><br><br>
<input type=&quot;submit&quot; value=&quot;Submit&quot;>
</form>

<%
If Request.Form(&quot;fnum&quot;)<>&quot;&quot; Then
Response.Write (&quot;the number you chose was &quot; & Request.Form(&quot;fnum&quot;) & &quot;!&quot;)
End If

%>
Response.Write &quot;<img src=&quot;images/Map/loc&quot; & Request.Form(&quot;fnum&quot;) & &quot;.gif>&quot;

</body>

this line is out of the %> plus another / will probably be needed

Response.Write &quot;<img src=&quot;images/Map/loc/&quot; & Request.Form(&quot;fnum&quot;) & &quot;.gif>&quot;
%> [bomb]
I may not get it the 1st or 2nd time,
but how sweet that 15th time can be.

I've moved the line into the %>.
I want the variable to be part of the file name
loc1.gif
loc2.gif
loc3.gif....
With the new setup I get..

Microsoft VBScript compilation error '800a0401'

Expected end of statement

/asp3/ch01/FIXFORM.ASP, line 13

Response.Write &quot;<img src=&quot;images/Map/loc&quot;& Request.Form(&quot;fnum&quot;)&&quot;.gif>&quot;
--------------------------^

Thanks all

try
Response.Write &quot;<img src='images/Map/loc&quot; & Request.Form(&quot;fnum&quot;)& &quot;.gif'>&quot;

this would would read then
<img src='images/Map/loc.gif'>

I like to write what I want to have generated out before I write the response.write, it finds errors before they occur many times

all you did here was forgot to end the src tag with a quote

Thanks for all the help. Everything works great however, Ive tried to add a background image. Does this look right

Response.Write (&quot;<br><img src='/images/Map/loc&quot; & Request.Form(&quot;fnum&quot;)& &quot;.gif' style=background-image: url('/images/Map/map.gif')>&quot;)


Should all &quot; be converted to ' when enclosed within the
<% %> except for the variable?


Thanks again

no not all the &quot; need to be '. just a good practice and commonly in some cases can cause wierd errors.
what exactly are you trying to do with the style here. you can't do the background to a img src either way but I'm curious if you are jsut trying to set the pages background or what. If that is the case

<html>
<head>
<style>
{
background-image: url(&quot;/images/Map/map.gif&quot;);
}
</style>
Response.Write (&quot;<br><img src='/images/Map/loc&quot; & Request.Form(&quot;fnum&quot;)& &quot;.gif'>&quot; [bomb]

I am messing with an application which will locate people on a building map. I have a test map with six locations and six different images showing an x in each location. the x would be the image called with the background image being the map. I'll have to try a different route

Thanks for everyones help
