making cells in tab2 = cells in tab1 in same workbook

[jimb01]

My workbook has 4 Tabs PCM Data, Analytical Data, QA-QC, & View Report. I am trying to get 2 cells in View Report = 2 cells in QA-QC. I am trying to get the date(B10) in tab View Report = Date in tab QA-QC(D9), I tried: ='QA-QC'!D9 That didn't work. I am also trying to have tab View Report cell Analyst(F10) = tab QA-QC cell =K9:M9 I tried ='QA-QC'!K9:M9 and I am get an error: #value! What do I need to do to make this work? Also If there is no date entered in tab QA-QC I want the date cell in tab View Report to be blank. the password for the attachment is 12345.Please feel free to look at the file.
