Variables working within Lectora, but not

We run Lectora 2006 and use an action to populate a new variable with the current time from the standard CurrentTime Variable which works fine. We then use an action to add say 60 minutes to the new variable. This is done because we want to delay the learner from completing a task for a certain period of time.From within Lectora in Run-Mode the variables have been created and the current time populates to the new variable fine, on the next page the variable happily takes the current time and adds the pre-defined number of hours. If we publish that to html and then run it within explorer we get the current time to populate correctly, however the adding of additional minutes displays still as the current time, BUT displays the additional minutes as a number after it (effectively concatenating).example is current time 10:00 altered time then displays as 10:0060 (the 60 adds 60 minutes), each time you refresh the page it adds another 60 to the end, so after 3 refreshed of the page you can end up with 10:00606060.NOW, in saying all that, the documentation does say that if a variable is told to add detail and it is numeric, it does addition (10:00 + 60 minutes = 11:00), however if it feels it is text, it will concatenate the 2 pieces of text, hence 10:00 plus 60 makes 10:0060.Seems the documentation makes a bit of sense, BUT it does what we wish to achieve within Lectora itself, OR for that matter also if you publish to CD-ROM (which for those that have not done this, creates a folder with lectorapreview.exe and the .awt file for the content)I have tested this from on Windows NT with Internet Explorer 5.5, Windows XP with Internet Explorer 6.0, even Mac OSX Safari and MacOSX Mozilla. All concatenate the time with the pre-defined number.Does anyone know how or if we can get around the concatenating?
