Hi ,
I have been stuck up with the following issues.
Scenario:
I have a formula box where user enters the formula for example :
(plant1*2+plant2*3) and then user clicks on validate button.
I am replacing plant1/plant2 variables by 1 and trying to get the output as 5. But its giving NaN. I know that the above formula is a string . But i want to know is there any way we can achieve the output as number when forumla is given by the user.
Thanks in advance.
