    <p>I have set up a page that includes 5 different variables that will be chosen by a dropbox in html. I am trying to get the Get QPE button to use all the variables chosen, and insert them into a web address to create a map. But the url is showing the parameters as "undefined"- <a href="http://nmq.ou.edu/cgi-bin/tools_QPE.cgi?1+0+2+undefined+undefined+undefined+undefined+0+0+34.50+-114.00+32.50+800+632+4101+0+0+1+0+Q2RAD_HSR+Q2RAD_HSR_GC+undefined+english+none+CNTY" rel="nofollow">http://nmq.ou.edu/cgi-bin/tools_QPE.cgi?1+0+2+undefined+undefined+undefined+undefined+0+0+34.50+-114.00+32.50+800+632+4101+0+0+1+0+Q2RAD_HSR+Q2RAD_HSR_GC+undefined+english+none+CNTY</a>. How do I get my selection to be read by the file? Here is code for one of the variables and the JS that I have.</p> <pre><code>&lt;p&gt;QPE - Gauge Adj.

    1. COYou're not passing any parameters into your `get_qpe()` function. That's why those variables are being returned as `undefined`.

    3. COWhat Nick said is correct. You should also look into your <form> tags. You have 2 "<form>" tags inside of your "<form>", no form tags get closed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
