extracting an index part II

[vbcandies]

I am trying to create a function GetIndex that will:

scan the controls (indexed controls) of a provided FRAME (using me.controls and the .container property) and on error resume to limit to controls in the provided frame
look for a specific indexed control and determine true/false if it is within the specified indexed frame:

GetIndex(frame, Frameindex, control, Cindex)

example: frame frmDogLeg(3) has optbut(0), optbut(2), optbut(5), optbut(11) in it

then GetIndex(frmDogLeg, 3, optbut , 2) should return TRUE
GetIndex(frmDogLeg, 3, optbut , 7) should return False

Note that I need to specify the indexes as separate numbers. I seem to get close, but keep going around in circles.
