Expected wavename error while using KillWaves in function

Hi all,

I have the following code which runs fine in general:

function processForceImage(scaledwave,d)
String scaledwave
variable d
variable n=1,m=1,c, k=1
Wave yourwave=::$scaledwave

    //clean the folder first, NEXT COMMAND IS DANGEROUS, MAKE SURE YOU ARE IN RIGHT FOLDER FIRST
Variable x=0
Prompt x, "Kill Waves? (1 if yes, 0 if no)"
DoPrompt "Kill Waves?", x
if (x==1)
    KillWaves/A
endif

FFT/OUT=3/WINF=Hanning/DEST=W_FFT  yourwave
        FFT/ROWS/DEST=$(scaledwave+"_FFTrows") yourwave         //FFT is complex
WaveTransform magnitude  $(scaledwave+"_FFTrows")
Rename M_Magnitude,$(scaledwave+"_FFTrows_mag")
SumDimension/D=0/Y=-1/DEST=$(scaledwave+"_FFTrows_sum") $(scaledwave+"_FFTrows_mag")
SetScale/I x 0,10.235,"nm", $(scaledwave+"_FFTrows_sum")  //specific to this image
Duplicate   yourwave $(scaledwave+"_invert")
wave wave2 = $(scaledwave+"_invert")
wave2 = yourwave[q][p]
Duplicate   wave2 $(scaledwave+"_1D")
Redimension/N=4194304 $(scaledwave+"_1D")   //specific to this image i.e. 2048x2048
FFT/OUT=1/WINF=Hanning/DEST=$(scaledwave+"_1D_FFT")  $(scaledwave+"_1D")
    //Repeat 2&3 for one quadrant

    //loop for each sub-region
for (n=1; n<d+1; n+=1)
    for(m=1; m<d+1; m+=1)
        c=2048/d
        Make/O/N=(c,c) $(scaledwave+"_"+num2str(k))
        wave wave3 = $(scaledwave+"_"+num2str(k))
        wave3 = wave2[p+(m-1)*2048/d][q+(n-1)*2048/d]
        SetScale/P x 0,0.0488519785051295,"nm", $(scaledwave+"_"+num2str(k));DelayUpdate  //this image
        SetScale/P y 0,0.0488519785051295,"nm", $(scaledwave+"_"+num2str(k))                    //this image
        FFT/COLS/DEST=$(scaledwave+"_"+num2str(k)+"_FFT")  $(scaledwave+"_"+num2str(k)) //COLS since using the inverted image
                //Now sum the columns
        WaveTransform magnitude  $(scaledwave+"_"+num2str(k)+"_FFT")
        Rename M_Magnitude,$(scaledwave+"_"+num2str(k)+"_FFT_mag")
        SumDimension/D=1/Y=-1/DEST=$(scaledwave+"_"+num2str(k)+"_FFTcols_sum") $(scaledwave+"_"+num2str(k)+"_FFT_mag")
        SetScale/I x 0,10.235,"nm", $(scaledwave+"_"+num2str(k)+"_FFTcols_sum")     //this image
            //Convert to 1D and FFT
        Duplicate   $(scaledwave+"_"+num2str(k))  $(scaledwave+"_"+num2str(k)+"_1D")
        variable b = 2048*2048/d/d
        Redimension/N=(b) $(scaledwave+"_"+num2str(k)+"_1D")                //this image
        FFT/OUT=1/WINF=Hanning/DEST=$(scaledwave+"_"+num2str(k)+"_1D_FFT")  $(scaledwave+"_"+num2str(k)+"_1D")
        KillWaves $(scaledwave+"_"+num2str(k)), $(scaledwave+"_"+num2str(k)+"_FFT") , $(scaledwave+"_"+num2str(k)+"_1D")
        KillWaves $(scaledwave+"_"+num2str(k)+"_FFT_mag"), $(scaledwave+"_"+num2str(k)+"_1D")
        k=k+1
    endfor
    m=1
endfor

KillWaves $(scaledwave+"_FFTrows"), $(scaledwave+"_FFTrows_mag"), $(scaledwave+"_invert"),$(scaledwave+"_1D"),W_FFT
end

The only problem is that I get the following error: While executing KillWaves, the following error occurred: expected wave name

Using the debugger, I can see that the problem is 7 lines from the end in the For loop with the command:
KillWaves $(scaledwave+"_"+num2str(k)+"_FFT_mag"), $(scaledwave+"_"+num2str(k)+"_1D")

It can't find $(scaledwave+"_"+num2str(k)+"_FFT_mag") even though every other wave in the 3 KillWaves command works fine. I know the name is correct since I cut and pasted it from earlier in the code and I can see in the debugger that at that step, the wave with that name exists in the current data folder. I don't understand why it can't find this wave but can find every other wave with same $name.

Does anyone see my error?

Thanks,
Brandon
