 jit.gl.shader: GLSL attribute name not valid: 'sizeAttr'

when declaring a VERTEX_ATTR in my shader with the following code. 

I have done this already other times and it was working, now suddenly doesn't work in this code. Can you spot the error? 

I tried also an empty shader and just declaring the vertex attribute gives the error.

This is the jit.gl.mesh to which the shader is attached:

jit.gl.mesh game @draw_mode points @color 0.7 0.7 0. 7 0.7 @shader shady1 @texture particleTex @blend_enable 1 @depth_enable 0 @blend alphaadd

        <program name="vp" type="vertex">

Hi all,

vertex-attribute-error-in-shader

have you declared the vertex attribute variable in the relevant shader program? e.g. :

if that's not it, please post the patch and shader and i'll take a look.

also, in new to Max 8 is an example of this technique. search browser for: custom.vertex.attribute.maxpat

have you declared the vertex attribute variable in the relevant shader program? e.g. :
attribute float sizeAttr;

if that's not it, please post the patch and shader and i'll take a look.

Thank you Rob, for some reason I tried again today and the patch worked. 

Must have been something getting temporarily screwed in my OpenGL.
