Error 'invalid number' ???

Question

I just wanted to do this:
SELECT      PROJ_TASK.PROJECTID,
     PROJ_TASK.TASKUNIQUEID,
     '\\ANDREWS\DD\op\op-l\Service_Orders\' + PROJ_TASK.TEXT_26 + '.pdf' AS Path
FROM PROJ_TASK
But it gives me an error highlighting '.pdf' ... Im just trying to append that string with that field name.
My whole query is:
SELECT      PROJ_TASK.PROJECTID,
     PROJ_TASK.TASKUNIQUEID,
     '\\ANDREWS\DD\op\op-l\Service_Orders\' + PROJ_TASK.TEXT_26 + '.pdf', PROJ_TASK.TEXT_26 + ' ' + 'F OP-L 816 Service Order form'
FROM PROJECT
LEFT JOIN PROJ_TASK ON PROJ_TASK.PROJECTID=PROJECT.PROJECTID
WHERE (PROJECT.CATEGORY = 'SERVICE' OR PROJECT.CATEGORY = 'INSTALL') AND TEXT_26 IS NOT NULL
AND SUBSTR(PROJ_TASK.TEXT_26, -2) <> 'xx'
AND NOT EXISTS(SELECT * FROM TBL_TASK_LINKS WHERE TBL_TASK_LINKS.PROJECTID = PROJ_TASK.PROJECTID AND TBL_TASK_LINKS.TASKUNIQUEID = PROJ_TASK.TASKUNIQUEID AND TBL_TASK_LINKS.LINKURL = '\\ANDREWS\DD\op\op-l\Service_Orders\' + PROJ_TASK.TEXT_26 + '.pdf' AND TBL_TASK_LINKS.LINKDESC = PROJ_TASK.TEXT_26 + ' ' + 'F OP-L 816 Service Order form');
END;
But I get errors...can someone take a look please...
thanks!

'\\ANDREWS\DD\op\op-l\Service_Orders\' + PROJ_TASK.TEXT_26 + '.pdf' AS Path What is this line ? are you trying to concatenate strings ? If so, then the syntax is
'\\ANDREWS\DD\op\op-l\Service_Orders\' || PROJ_TASK.TEXT_26 || '.pdf' AS Path
