EPMLINK in conditional formula

Hi experts:

     I have a excell EPM cell with this formula:

      IF(A1="AA";EPMLINK("MY_MODEL","PATH/FILE.xlsm";"LINK_TEXT");"NO LINK")

  So, when A1 cell contains AA, my cell show LINK_TEXT but when I double-click on it, I can navigate to PATH/FILE.xlsm

Do you can help me?

Thanks in advance,
