Subscribt Problems

I have a subscribt problem in the following equation:

ms car =
SUM(tours ij opeak[i!,J!,car]+tours ij peak[i!,J!,car]) / SUM(tours ij opeak[i!,J!,mode!]+tours ij peak[i!,J!,mode!])

When I check the syntax the equation is ok, when I check the model it isn't.

The error message is the following: -i-appears more than once on LHS.

What does it mean? Did anybody have similar problems?

Greetings,
Anna

It may be that the error is not in this equation.

When you check the model, use the drop down box at the bottom of the equation editor and see if you can select another equation that might be the cause.

Thanks Tony, seems that I found the source of the error!
