Hi i am a beginner

I hope you can help me.

1. I am using a listview with three columns (column1 =name, column2=carpetneeded, column3=costcarpet) in the properties i have chosen to select the whole row
when i have selected a whole row i want to get the item value (eg 54) which i have selected in column 2 to be calculated with something like the value in a textbox.

what command would i use

eg calculation

textbox1.Text = Val(textbox1.Text) - (selected item in the column)

i hope you understand what i mean


2. Could you please tell me i have a form and a want to make a button which will clear out everything in the form eg textboxes, listview, as if the form had just started

3. The other thing is could you tell me if i have a form open how could i open another one, so i have two forms opened at the same time.
