The XPath expression in the "ref" attribute is not evaluated at the same time as XPath expressions in the XSLT document are. It is evaluated by the XForms engine later on, which does not have any information about the $entryPosition variable. What you have to do is generate an XPath expression without variables. You can do this as follows:
ref="/e:envelope/ts:CDETimesheet/ts:CDETimesheetEntries/ts:CDETimesheetEntry[{$entryPosition}]/ts:Projects/ts:Project/ts:Hours"
This works because all element attributes in XSLT are interpreted as
"attribute value templates", which means that they are templates where
values within brackets {} are evaluated and replaced within the
template. With the example above, {$entryPosition} is replaced with
the value of the $entryPosition variable in the attribute.-Erik
