I have a popup form which comes up on change of combo item, I am not able to see the images on the form every time.Even the operations on the form are also not happening every time. Can i get some ideas for this? Thanks in advance, Sireesha.

We need to validate an expression which contains all the arithematic operators, conditional operators, logical operators, grouping such as '()' and '{}' For example: A+B = 10 AND (B*C)/d = 56 Thanks in advance
