I have three edit boxes. Edit 1 2 and 3. what I'm trying to achieve is:-

If editbox 2 is equal or greater than Editbox 1 then edit box 3 equals nil. Else, Edit box 3 equals Edit box 1 less Edit Box 2.

What ever I do I can't get the syntax right.

Many thanks

Nick

if StrToInt(edit2.Text) >= StrToInt(edit1.Text)  then
  edit1.Text :=''
else edit3.text := IntToStr( StrToInt(edit1.Text) - StrToInt(edit2.Text) );

in the case your'e talking about numbers...

i don't know why but in the then cluase it didn't put the double '('   ' )and switched it with "

so pay attention::::



if StrToInt(edit2.Text) >= StrToInt(edit1.Text)  then
  edit3.Text :=' '  //i mean put nothing in the edit 3 text box
else edit3.text := IntToStr( StrToInt(edit1.Text) - StrToInt(edit2.Text) );
