2 primary antibodies, both binding actin...they shouldn't be :(

I did a western the other week and used two primary antibodies (mouse anti-actin and rabbit anti-IL7R) and then used two secondaries, (goat anti-mouse, and goat anti-rabbit). Both secondaries are labelled with IR dyes, the anti mouse is 680nm, the anti-rabbit is 800nm.
I admit, I transferred the proteins to PVDF, then incubated with both primaries together, and then both secondaries together. I ended up with a lovely yellow band at the size of actin, and nothing at the size of IL-7R. Have I screwed it up? Should I incubate everything separately? Which order would be best? I figured since I had different species and targets I would be ok to incubate it all together....

if not, then you may have to tweak the protocol.

Also, do you know for sure that the sample you used expresses IL7R?
then heaven will be yours, before you meet your end
