Expanding Bar Graph

I am using the followng code to create a horizontal bar graph inside a table cell containing a subform. I want the height of the bar to "grow" when the subform grows. The subform grows when the user enters more than one line of data in a different cell in the same row.

Form1.Table1.ActionItemGrp.Row5.PercentCompleteSubform.HiddenPercent::calculate - (JavaScript, client)if(PercentComplete.rawValue !==null){
 this.rawValue = PercentComplete.rawValue;
 var vScore = 0; if (this.rawValue == 1) { vScore = vScore + 1; }if (this.rawValue == 2) { vScore = vScore + 2; }if (this.rawValue == 3) { vScore = vScore + 3; }if (this.rawValue == 4) { vScore = vScore + 4; }if (this.rawValue == 5) { vScore = vScore + 5; }if (this.rawValue == 6) { vScore = vScore + 6; }if (this.rawValue == 7) { vScore = vScore + 7; }if (this.rawValue == 8) { vScore = vScore + 8; }if (this.rawValue == 9) { vScore = vScore + 9; }if (this.rawValue == 10) { vScore = vScore + 10; }
 var vWidth = (vScore/10) * 1.5109; // width of the subform
 this.resolveNode("Table1.ActionItemGrp.Row5.PercentCompleteSubform.Bar").w = vWidth + "in";
 this.resolveNode("Table1.ActionItemGrp.Row5.PercentCompleteSubform.Bar").x = ".01in"; // relative to the subform}

I want the height of the bar (rectangle) to grow the same height as the subform it is in when it expands.

Thank you
