# Help needed on label.caption

Hello,
I need some help with the following:

A length is input in mm...eg/83
A diameter is input in mm....eg/3.2
A button is selected called calculate..

The values are formulated as:
r=(diameter/10)*0.5
volume1=3.141*(r^2)*length/10
The answer is displayed in  (LABEL4.CAPTION)

Then the following calculation is done on the same form1..
A length is input in mm...eg 2500
A diameter is input in mm ...eg 6
# of cavities is input ......eg 2 (no units)
A pressure is input in Bar ..eg 85
A time is input in sec     ..eg 14
Another button is selected called calculate...

The values are formulated as:

r=(diameter/10)*0.5
volume2 = 3.141*(r^2)*length/10  ***displayed at label14.caption as a result***

total volume = (VOLUME1 * #ofcavities)+VOLUME2  ****Note volume 1 from above calculation***

normal liters = total volume/1000 * pressure

liters/min = (normal liters * 60) / cycle time

Question:  How do i pass (volume1 answer is a displayed result label4.caption)
into the 2nd set of calculations.
How do I pass (Volume2 answer is a displayed result label14.caption)
into the above calculation even when its already used to
display a result?

Note: I am using edit boxes for number entry and label.captions to display
results.
Does someone an idea how to program these???

Hi!

YOu do something like this.////

R := Something * StrToInt(Label4.Caption);

or

R := Something * StrToFloat(Label4.Caption);
