Hi!

I am working my way through the Procedural Text Animation tutorial. I keep getting this error in one of my Point SOPs:

Error: Channel evaluation error Undefined variable (/obj/FirstIPop/point_modify_prs/val1i1).

The error seems to be generated from my attempts to randomize a custom scale attribute with an expression like so:

$SCALE1 * fit01(rand($PT * 234),0.7,1.5)

What is confusing to me is that I copied the expression exactly from the tutorial! What am I doing wrong? I've included the hip with this posting.

either change attribcreate_scale type to Float and Size to 3
or leave it at Vector, but change $SCALE1, 2, 3 to $SCALEX, Y, Z in point_modify_prs Point SOP

since float3 attribute variables add numbers and vector attributes add X,Y,Z after the variable name
