Calling out value from a container

System

If I have a datacapture like this:

<!DOCTYPE data-capture-requirements SYSTEM "/interwoven/iw-home/local/config/datacapture5.0.dtd">
<data-capture-requirements type="content" name="two_column_description">
<ruleset name="description::two_column_description">
<description>This section will display the description of your content</description>
<container name="title" combination="and">
<label>Title Text</label>
<item name="col1Header">
<label>Left Side Title Text</label>
<description>Enter Main Title Header Column 1 Header Name</description>
<text required="f" size="50" maxlength="30"></text>
</item>
<item name="col2Header">
<label>Right Side Title Text</label>
<description>Enter Main Title Header Column 2 Header Name</description>
<text required="f" size="50" maxlength="30"></text>
</item>
</container>
</ruleset>
</data-capture-requirements>


How would I source the value of col1Header in the .tpl? I have tried:

my $titleLeftText=iwpt_dcr_value("title.col1Header");
my $titleLeftText=iwpt_dcr_value("dcr.title.col1Header");

etc. and I can't source it with the container tag around it? I can only source it without the container tag around it by dcr.col1Header
