Missing Start/End Qualifiers

[redmann11]

I receive the error "Missing start or end of block syntax" on my TI-89 when running a program. I understand that I am missing the start/end qualifiers, and I need help placing them. Here is the program:

:Prgm
:Disp "lower limit"
:Input a
:Disp "upper limit"
:Input b
:Disp "n subintervals"
:Disp "enter even n"
:Input n
:0->s
:0->v
:(b-a)/n->w
:For j,1,n/2
:a+2j*w->r
:(p+r)/2->m
:y1(p)->p
:y1(r)->r
:y1(m)->m
:s+w*(p+4m+r)/3->s
:v+w*(p+2m+r)/2->v
:Disp "simpson rule"
:Disp s
:Disp "trapezoidal rule"
:Disp v
:EndPrgm


Thanks for the help!

Hi redmann11,

I think you need a matching EndFor for your For loop. My guess would be it belongs just above the statement that reads

Disp "simpson rule"

Hope this helps!
