I can't for the life of me see why I can not read the postPrioity outside the while loop. I tried "export postPrioity="500"" still didn't work. Any ideas? -- or in plan text -- <pre><code>#!/bin/bash cat "/files.txt" | while read namesInFile; do postPrioity="500" #This one shows the "$postPrioity" varible, as '500' echo "weeeeeeeeee ---> $postPrioity <--- 1" done #This one comes up with "" as the $postPrioity varible. GRRR echo "weeeeeeeeee ---> $postPrioity <--- 2" </code></pre> OUTPUT: (I only have 3 file names in files.txt) <pre><code>weeeeeeeeee ---> 500 <--- 1 weeeeeeeeee ---> 500 <--- 1 weeeeeeeeee ---> 500 <--- 1 weeeeeeeeee ---> <--- 2 </code></pre>

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.
