creating text wave from two waves

I'd like to take the output of two waves, and create a text wave with the same number of points as both waves in the format wave1:wave2

Example waves:

xel[0]= {8.22328,10.4223}
yel[0]= {13.397,25.3365}

basically the resultant wave (time_in_minsess) should return
8:13
10:25

however I'm getting a wave with 8:13 then 10:25 repeated 127 times (i.e. 128 numbers long)
I'm also getting an index out of range error for xel even though the wave time_in_minsess is created

Here is a code snippet that I'm having difficulty with:

Make /O/T  = (numpnts(xel)) time_in_minsess
time_in_minsess =  num2str (floor(xel)) + ":" + (num2str(round(yel)))

     
Try:

Make /O/T/N= (numpnts(xel)) time_in_minsess =  num2str (floor(xel[p])) + ":" + (num2str(round(yel[p])))

You probably found out already from Jim's post. But in the end you were just missing the /N flag, which is used to define the number of points.
If you are unsure about the use of flags for a specific command, you can look up the list of possible parameters in the 'Command Help' part of the help browser quickly.

thanks, I mistakenly thought that when making text waves "/T=" would replace the "/N= " flag to determine the size of the wave.
