Thank you.
My problem was solved with your help.

Warning: units in equation for - labor index
Lookup - labor lookup table- used with dimensioned argument person

Because of the compatibility of other relevant calculations, i must use dmnl unit

Hi
When I check my model, I encountered with one warning in unit check.
how can I remove the warning
I try to remove with suppresses warnings But did not work

I think I do not know one of the main points about the lookup table

excuse me how i should fix my formula to run my model
i want for example for first year GDP*0.0002 and give my first output in graph?
in my graph: axis are years in the format Hijri Shamsi...and y axis are %GDP which invested on ICT sector

sorry
I forgot.

Hi
I have a problem in running my vensim model.
In my model, the result of the multiplication of the variable level GDP in a lookup table is a constant number.
But I know this amount should change over time!
Where is my model's bug???
Help me please

here is my vensim model

i have a structural equation modeling
i want to use my model numebr in vensim? can i?
the red arrow are my equation relation.
please help me?
I'm so confused

Hi I’d like to try to estimate the parameters of the my model from part of my model my strategy is to estimate separately the parameters, using regression and i dont now how i can estimate? I do not know how to enter the numbers I get through SEM in vensim Please send me if you have a training file ...

Thank you.

Hi
In many sample Vensim models, especially in the model guide files, I've seen sample Graphs which running on the same model screen.
How can I use this feature?

Hi
In my vensim model, I have a stock variable called service quantity.I want there is a value number between 0 and 1.
I used min function for this purpose but still, the answer is bigger than one.
Use min and max option in variable information window Did not make a difference.
please guide me.

Hi
I'm wondering why my Vensism software does not have sensitivity analyze option(No sensitivity icons, no toolbar)!?
I even re-install the software, but I'm still having problems
I use Vensim 6.4.
Thanks.

Thank you so much.

Despite all the changes and corrections, when I put the actual data about GDP growth along years in the lookup table, it seems that the output is still wrong.
GDP starts from zero point instead of 393.4 billion dollars!!

Thank you for your all your help.

Thank you so much for your valuable guides.

excuse me, How should I do this?

Hello
thanks for your help.
I modify growth rate = f ( time ) and I change units, but I still have a problem!

Yes x-axis is time and y-axis is GDP growth rate

hello
please help me
My lookup function f multiplies only one constant in growth rate the variable

Thanks for your attention.
I fix dimension and remove penetration rate and 100 from equations, but the number of internet site visitors are still fixed in 2200000, and does not increase properly?
Is there a problem with the formula?

I did all the hints but the problem has not been fixed yet!

thank you so much
