how to make label flash and not combobox

hi
is there away to have a label flash on a userform,have got code that makes combobox flash to remind people to enter data,this works fine,or so,would like the combox to flash up with message enter location and then return to normal combobox or make label flash /"enter location"when form comes on the screen but am not sure if it will interupt with program ie cause the screen to blink,the code is on frmissued and module 12
any help would be good
cheers colin
