macro question

[curseoflono]

ok this is gonna sound vague and abit silly but i hope sum one can follow what i want:

i have been experimenting with macros and the #show function

I have 3 trinkets which various combinations are equipped with different gear sets i use

Trinket A (always equiped) cooldown 1:30

Trinket B Cooldown 2:00

Trinket C Cooldown 2:00

(trinkets B+C change with each other depending on the situation)

I made a macro that will use these items (no matter which combination is equipped) all at same time (as the effects are beneficial and most effective when stacked)

/use a
/use b
/use c

Combinations will ALWAYS be either A+B or A+C

I want the cooldown count to always show the CD of the two longer trinkets (B+C) depending on which is equipped ofc

is there a way to make a command in the macro that will check to see which off the two (B or C) is actually equipped and choose which of the two CD timers to use on my interface?

I would assume this would be done with a IF command but am unsure about how it would be written.

Please note the actual trinkets in question are : A : dibris enigma . B : Gnomeregan auto blocker . and C : Figurine of collossas. CoolD'owns i have stated are un-accurate but serve to illustrate the problem.
