Loop Calculate and Count

Hi,

I've written a mathematical model using excel for a probability problem which requires the generation of random numbers. The idea is that I can run the model to see how long it takes for a certain condition is be satisfied.

At the moment I have to press F9 for the RAND() function to create a new set of numbers and then manually check to see if a particular cell is greater than or equal to 5. If it is not, I then repeat the process until the conditional is met.

It is also important for me to know how many times the random numbers were generated before my condition was met. I am currently counting the number of times I press F9 before the condition is met.

I have tried to figure out how to automate this process using a Macro but have failed miserably. I have no experience with Visual Basic and would appreciate any help available.

In summary, I want the following to take place in a macro:

1. Recalculate spreadsheet (i.e. generate random numbers)
2. Check if T24 is larger than or equal to 5
3. If No, loop back to Step 1
4. If Yes, stop macro and display number of iterations required

Many Thanks

You can force a calculation using code. Why not post a workbook if you have more stuff going on?
