Add to variable problem

Hello.I have a problem with the add to variable function.I want to make a series of entry boxes. These shall allow the user to type in numbers. In the last entry box the sum of all the other entry boxes shall be shown.I have used the following method for the entry boxes that shall be added up:Entry name: Entry_1Ass. variable names: a1On select/change: Modify variable - sum - var(a1) - add to variableThe last entry box (the one that sums up the others) have the following setting:Entry name: Entry_sumAss. variable names: sumallOn select/change: NoneThen I have used a text box with the following action to sum the entry boxes:Action name: AddAllOn: Mouse ClickAction: Change contentTarget: Entry_sumNew Content: sumThis works fine as long as the numbers entered in the entry boxes consist of one number/digit (eg. 1,2,3).When I try to enter numbers with 2 or more digits (eg. 10, 230) the total sum gets wrong.Eg. If I put in 11 in one of the entry boxes and click the text box to add up, then the total sum comes out as 12.Any one know what the problem is? Cant the add to variable function handle numbers with more that one digit?
