Part III of repeater

I have work out most of my problems with your help thanks to all assisted.

I hope this is the last piece of code I need help with.


With my repeater creating dynamic text boxes I need to place percentages in the appropriate text box per newly created textbox:


I have this for the first one

double amount = Convert.ToDouble(textBox.Text);
double subamount = Convert.ToDouble(textBox1.Text);
double per = (subamount  / amount) * 100;
percentage.text = per.ToString();

this work well for the first line.

I repeated the process

foreach (RepeaterItem item in Repeater1.Items)
{
string mbe = ((TextBox).item.FindControl("txtMBE")).Text;
if (mbe.ToString() == "Yes")
{
  string txtamount = ((TextBox)item.FindControl("txtAmount").Text;
  string txtmpercent = ((TextBox)item.FindControl("txtMPercent").Text;
  double dynamicamount = Convert.ToDouble();
  double dynamicsubamount = Convert.ToDouble();
  double dynamicpercent = (dynamicsubamount / dynamicamount) * 100;

My problem is how to write this to show in each newly created textbox where the txtMpercent appears 

}

}

When I build and to test. I placed a break to check and stepping into I get to this point in the code it shows me that it is calculating on each box but not writing to the assigned textboxes.

(by the way the Yes/No are dropdownlist)

What and I doing wrong.

other using string to work in my application.
