Excel help

[Teifiterror]

Hi, im trying to create an excel program to help me with some fluid dynamics and have bevome stuck on one portion.

I have a table of values that are altered depending on a single value, when the values change the chart that is created from them also changes.

In the chart I have a trendline showing me the equation for the line of that graph. Now I would like to know if there is a way to make excel automatically take out the equation form the trendline and use it without me having to retype it everytime??

Hope thats enough info, can give more if needed.

Thanks

i cant really do that, as its quite a mess at the moment and the information cant really be disclosed. I ve heard of macros that can do this, is there anywhere I can get them?
